[flexcoders] Retrieve current item on a DataGroup

[Jairo França]

I have a question that seems easy, but i can't solve.
I have a DataGroup with a custom ItemRenderer.
How can I retrieve the current item that was selected with a double 
click (something like a SelectedItem on a DataGrid)?
Can I retrieve the "itemRenderer" instance of the element?

My code is:




     <s:Group height="100%" width="100%">
             <s:Scroller height="100%" width="100%" id="scr">
                 <s:DataGroup id="dg" height="100%" width="100%" 
itemRenderer="myItemRenderer"
                              dataProvider="{_data}" 
doubleClickEnabled="true" doubleClick="dg_doubleClickHandler(event)">
                     <s:layout>
                         <s:TileLayout/>
                     </s:layout>
                 </s:DataGroup>
             </s:Scroller>
         </s:Group>
