I am using my own custom add row button on a grid, it runs some code, and then calls Rows.Add() on server side

 After the row is added I would like to jump to the first cell and be in the edit mode.

 I have the following client script but I can only get it to fire using the grids built in add functionality, how can i get this to fire using the approach above?

function dgSeminars_AfterRowInsert(gridName, rowId, index){
        var grid = igtbl_getGridById('dgSeminars');
        grid.Rows.getRow(rowId).getCell(1).beginEdit();
}
