disable check box in grid.. does not get disabled

I have this function to diable the check box in the gri.. the check box is the 4th column
function disableWelcomeEmailChk(name) {
    //alert("disableWelcomeEmailChk : " + name);
    for ( var i = 0; i < grid.getRowsNum(); i++ ) {
        if ( grid.getRowId(i) != null ){            
            grid.cellByIndex(i,3).setDisabled(true);        
        }
    }

}

But even after the grid is populated the check box column is not disable. When I put the alert message it gets disabled. so thef ucntion seems to work..it as if the grid is not populated when the function is initially called. the grid gets poplulated via ajax call

Thanks
