RowGroup jquery selector for group TR

RowGroup jquery selector for group TR

I am using the RowGroup extension and it works quite well (thanks for this!). I am trying to implement a collapse expand feature that I found, and the problem I am having is getting the jquery selector for the group to trigger.

When I use the inspector in Chrome on a group row, I see something like this:

<tr data-name="01 74 10" class="dtrg-group dtrg-start dtrg-level-0">
    <td colspan="8">01 74 10 (54)</td>
</tr>

Here is one selector I have tried, that seems like it should work:

$("tr.dtrg-group td").click( function () {
    alert("click");
}); 

The way my app works is:
- the table starts out with no data
- user clicks a btn which opens a modal dialog with a multiselect list of csi codes (categories of work)
- when user selects a code, I do an ajax call to get records with that code
- I loop through this list and call add rows with row.add

It uses bootstrap. Thinking that might be interfering, I have commented it out, with no change.

So- what could cause my jquery selector to fail?

What is particularly annoying is that there is a working example, and the code is essentially like mine, but simpler. I've always felt that if I have a working example and a non-working example, I should be able to spot the difference, but so far it has eluded me.
Simple working example I found

Here is my datatables declaration:

var addtable = $('#contaddedtable').DataTable(
{
    "dom": 'Bfrtip',
    "processing": true,

    drawCallback: function( settings ) {
      $.busyLoadFull("hide");
    },

    "columnDefs": 
    [{
        targets: 0,
        data: null,
        defaultContent: '',
        orderable: false,
        className: 'select-checkbox'
    }   
    ,{
        "targets": [1,2],
        "createdCell": function (td, cellData, rowData, row, col)
        {
            if ( rowData.inUse == 1 )
            {
                $(td).addClass('inUse');
            }
        }
    }]

    ,rowGroup: {
        dataSrc: ['CSI']
    ,startRender: function (rows, group) {
      var collapsed = !!collapsedGroups[group];

      rows.nodes().each(function (r) {
          r.style.display = collapsed ? 'none' : '';
      });    

      // Add category name to the <tr>. NOTE: Hardcoded colspan
      var csiString = csiAssocArr[group];
      return $('<tr/>')
          .append('<td colspan="8">' + group + ' (' + rows.count() + ')</td>')
          .attr('data-name', group)
          .toggleClass('collapsed', collapsed);
    }
    }
    ,"columns": 
    [
        {
            render: function(data, type, row){

                {
                    case "1":
                        prefClass = "preferred_cont";
                        break;

    I've got it working now. I had tried your exact code for the listener, which I had gotten from the example, but it failed because I had neglected to change "table" to my table var name.
    Sometimes it helps to have somebody else weigh in. Thanks for taking the time to help!
