ADG label for Grouping

Hi All,
This is my sample code:
<grids:dataProvider>
<mx:GroupingCollection2 id="gc">
<mx:grouping>
<mx:Grouping label="YEAR">
<mx:GroupingField name="FY"
groupingFunction="formFieldGroup" compareFunction="stringCompareFunction">
<mx:summaries>
<mx:SummaryRow summaryPlacement="group"
summaryObjectFunction="summObjFuncTitle">
<mx:fields>
<mx:SummaryField2 dataField="FY"
/>
</mx:fields>
</mx:SummaryRow>
</mx:summaries>
</mx:GroupingField>
</mx:Grouping>
</mx:grouping>
</mx:GroupingCollection2>
</grids:dataProvider>

private function summObjFuncTitle():SummaryObject {
// Define the object containing the summary data.
var obj:SummaryObject = new SummaryObject();
// Add a field containing a value for the Territory_Rep
column.
obj.COLUMN_01 = "OCT"; //Here I want to include the year in
the label as OCT 2014
return obj;

I am setting the label with summObjFuncTitle function.
The year show as the root name for each tree.
How can i get the value of my FY field (year) in the summaryObjectFunction?
Is this possible?
Thanks
