Tratando de obtener un simple show / hide en marcha. Está funcionando en js fiddle, simplemente no en mi aplicación.

En mis vistas / user_steps / interests.html.erb

<code><label class="checkbox">
 <input id="user_holiday_ids_" name="user[holiday_ids][]" type="checkbox" value="2" />
 Valentine Day
</label>
<div style="display:none;">
    Whatever you have to capture here<input type="text" id="foo" />
</div>

<label class="checkbox">
 <input id="user_holiday_ids_" name="user[holiday_ids][]" type="checkbox" value="3" />

<code>$(".checkbox").click(function(){
   $(this).next("div").toggle();  
});
