Unable to get edit event on cells in sub_grid_row grid

We are creating a sub grid programmatically through javascript and have run into an issue where double-clicking on a cell in the sub-grid does not trigger the edit cell functionality.

Referring to this javascript from dhtmlxgrid.js (appx line 1432, when script is unminified in google chrome):

this.obj.ondblclick = function(a) {
        if (!this.grid.wasDblClicked(a || window.event))
            return !1;
        if (this.grid._dclE) {
            var b = this.grid.getFirstParentOfType(_isIE ? event.srcElement : a.target, 
            b == this.grid.row && this.grid.editCell(a || window.event)
        (a || event).cancelBubble = !0;
        if (_isOpera)
            return !1

it appears that it fails at the “b == this.grid.row” check, because this.grid.row is always null when this event fires in the sub-grid. B is set to the proper TR element that the double click event fired on.

Any ideas what could be wrong here?
