No jqgrid para treegrid, quando clico no valor exibido em uma célula da coluna expandColumn: 'name' para editá-lo, estou recebendo o html do conteúdo dentro da célul

O conteúdo html que recebo é: -

<div class="tree-wrap tree-wrap-ltr" style="width: 54px;"><div style="left: 36px;" class="ui-icon ui-icon-radio-off tree-leaf treeclick"></div></div><span class="cell-wrapperleaf">Sub-subtask1</span>

Embora meu valor real seja apenas: - Subtarefa1

Minha configuração de grade é a seguinte: -

jQuery("#tree").jqGrid({
        url:'json/jsonSamplePots.json',
        datatype: "json",
        mtype:'GET',

        colModel: [
            {name:'id',width: 30, editable:false, align:"right",sortable:false, hidden: true, key: true},
            {name:'no',width:80, editable:false, align:"left", sortable:true, sorttype:"int"},

        ],
        rowNum:10,
        rowList:[10,20,30],

        treeGrid: true,
