Tengo este botón:

<div class="btn-group bootstrap-select show-tick span12 reg-form-control validate[required]">
<button id="control-qid13228" type="button" class="btn dropdown-toggle btn-bootstrap" data-toggle="dropdown" data-id="qid13228">
    <div class="filter-option pull-left">3 of 4 selected</div>&nbsp;<div class="caret"></div>
</button>
<div class="dropdown-menu open" style="max-height: 249px; overflow: hidden; min-height: 92px;">
    <ul class="dropdown-menu inner" role="menu" style="max-height: 237px; overflow-y: auto; min-height: 80px;">
        <li rel="0" class="selected"><a tabindex="0" onclick="update_reg_multi_click('qid13228','basketball');" style=""><span class="text">basketball</span><i class="glyphicon glyphicon-ok icon-ok check-mark"></i></a></li>
        <li rel="1"><a tabindex="0" onclick="update_reg_multi_click('qid13228','baseball');" style=""><span class="text">baseball</span><i class="glyphicon glyphicon-ok icon-ok check-mark"></i></a></li>
        <li rel="2" class="selected"><a tabindex="0" onclick="update_reg_multi_click('qid13228','football');" style=""><span class="text">football</span><i class="glyphicon glyphicon-ok icon-ok check-mark"></i></a></li>
        <li rel="3" class="selected"><a tabindex="0" onclick="update_reg_multi_click('qid13228','hockey');" style=""><span class="text">hockey</span><i class="glyphicon glyphicon-ok icon-ok check-mark"></i></a></li>
    </ul>
</div>

He intentado hacer clic programáticamente usando JQUERY

    <script>
$(document).ready(function(){
    $("#control-qid13228").click();
});                     
    </script>

También he intentado un clic de disparo:

    <script>
$(document).ready(function(){
    $("#control-qid13228").trigger("click");
});                     
    </script>

Ninguno parece funcionar. Hacer clic con mi mouse, por supuesto, funciona bien. ¿Algunas ideas?

Solo un aviso, esto es parte de un intento de abordar un problema diferente que tengo con bootstrap-select, abordado en este script en progreso.

        function update_reg_multi_click(id,myvalue) 
        {
            //
            var main_id = $("#" + id);
            var main_id_control = $("#control-" + id);
            var main_id_option = $("#" + id + " " + ">" + " " + "option");
            var main_id_value = $(main_id).val();               
            var this_div = $(this);
            if(main_id_value != null){
                var main_id_value_list = $("#" + id).val().toString();
                var test_if_in_list=main_id_value_list.toLowerCase().indexOf(myvalue) >= 0;
                if(test_if_in_list){
                    //alert('in list');
                    $(main_id_option).each(function() {
                        $(this).removeAttr("selected");
                    });                         
                    var newlist = remove_reg_val(main_id_value_list,myvalue,",");                           
                    $.each(newlist.split(','), function(){
                      var option_to_set = $("#" + id + " " + "option[value="+this+"]");
                      $(option_to_set).attr('selected','selected');
                    });
                    $(main_id).selectpicker('refresh');     
                }
                else{
                    //alert('not in list');                     
                    $(main_id_option).each(function() {
                        $(this).removeAttr("selected");
                    });                             
                    //alert(main_id_value_list);
                    var newlist = main_id_value_list + ","+myvalue;
                    //alert(newlist);
                    $.each(newlist.split(','), function(){
                      var option_to_set = $("#" + id + " " + "option[value="+this+"]");
                      $(option_to_set).attr('selected','selected');
                    });
                    $(main_id).selectpicker('refresh');                                 
                }
            }
            else{
                var newlist = myvalue;
                $.each(newlist.split(','), function(){
                  var option_to_set = $("#" + id + " " + "option[value="+this+"]");
                  $(option_to_set).attr('selected','selected');
                });
                $(main_id).selectpicker('refresh');                                                           
            }                           
        }

Aquí está la selección que estoy tratando de abordar:

<select name="qid13228" id="qid13228" class="selectpicker span12 reg-form-control validate[required]" data-style="btn-bootstrap" multiple="" data-selected-text-format="count&gt;2" style="display: none;">

<option value="basketball" onClick="update_reg_multi_click('qid13228','basketball');" selected="selected">basketball</option>

<option value="baseball" onClick="update_reg_multi_click('qid13228','baseball');">baseball</option>

<option value="football" onClick="update_reg_multi_click('qid13228','football');">football</option>

<option value="hockey" onClick="update_reg_multi_click('qid13228','hockey');" selected="selected">hockey</option>

</select>
