Get Grids Cell

Hi I create Grids and I want get cell value when double click.  Add this method  but when I double click grid row . No Trigger anything so I can't  get cell. Method: debugger; var virtualGridNode = document.createDocumentFragment(); clientControlsFactory.createControl("Aras.Client.Controls.Public.GridContainer", { connectNode: virtualGridNode}, function(control) { grid = gridApplet = control; gridReady = true; clientControlsFactory.on(grid, { "gridDoubleClick": onDoubleClick, "gridMenuClick": function(cmdId, rowId, col) { return onRelationshipPopupMenuClicked(cmdId, rowId, col); }, "gridKeyPress": onKeyPressed }); }); function onDoubleClick(rowId) { if (isEditMode) { return true; } if (computeCorrectControlState("show_item") && showRelatedItemById(rowId)) { return true; } else if (computeCorrectControlState("show_relationship")) { return showRelationshipById(rowId); } return false; } function onKeyPressed(key) { var keyCode = key.keyCode; if (keyCode == 9 && !key.shiftKey) { if (grid.focus_Experimental.isLastCell()) { bCreateNew = true; } } }
