Combo selected index in Grid

Hi all

I'm havins some difficulties in here...

I have a grid, and one of the columns is a combo box, the 9th

var listTreinadores = new AW.UI.List;
listTreinadores.setItemText(dataTreinadores[1]);
listTreinadores.setItemValue(dataTreinadores[0]); listTreinadores.setItemCount(dataTreinadores[1].length);
obj.setCellTemplate(new AW.Templates.Combo, 9);
obj.setPopupTemplate(listTreinadores, 9);

I want to get the index selected or the value in a combo in a row

with obj.getCellText(9,i) i only can get the text of the combo on the i row

Thanks in advance
