$(cell).index() INTERMITTENTLY returns incorrect column index

[Tim R]

EDIT: This was happening because the cell sometimes contained a DIV, and the DIV, not the TD, was the event target, which messed up the code that gets the cell-index.  
  
IIt may be my error, or it could be a problem with the grid or jQuery.  My code is shown below.  I'm clicking on the same column, choosing a different row at random, and every so often, the wrong column-index is returned. I cannot figure out why it works most of the time, but not always.  I'm clicking on a column whose index is 7. Sometimes zero is returned.

function addCellClickEventListener() {

    var grid = $('#grid').data('kendoGrid');

    $(grid.tbody).on('click', "> tr:not(.k-grouping-row, .k-detail-row, .k-group-footer) ", function (e) {

        popup(e);

    }); 

}

 

 

function popup(e) {    

    var cell = e.target;

    var ix = $(cell).index(); 

    assert((ix != 0), "index must be greater than zero"); 

}

 

 

function assert(val, msg) {

    if (!val) {

        alert(msg);

        return false;
    }

    return true;

}
