New rows are not editable

My whole grid is editable, but when I add a new row I am not able to select any cells within it. How do I fix this? Part of my code is below:

function add(){

var serial = gridData.legth-1;

gridObj.onRowAdded = function(row){
window.status = "Row added: " + row;
this.setCellText(myRow, row);
gridObj.setCellEditable(true);
}

gridObj.addRow(serial++);
gridObj.setCellEditable(true);
gridObj.refresh();
}

Nevermind, I fixed my own error:
this.setCellText(myRow,0, row);
