duplicate item to a flex datagrid

How do I duplicate a item in a Datagrid? I have a custom class (someClass) for the item of ItemList. The way is coded below the new item that shows up is in fact the SAME item selected, instead of a NEW item. I don't know how to clone the items of the list, can anyone please help me?

	<fx:Script>
		<![CDATA[
			protected function Duplicar_Item_clickHandler(event:MouseEvent):void
			{
				var tarVo:someClass= new someClass();
				tarVo = productGrid.dataProvider.getItemAt(productGrid.selectedIndex);	
				productGrid.dataProvider.addItemAt(tarVo,productGrid.selectedIndex);	
			}
			
		]]>

		<s:Button label= "Duplicate Item"
				  click="Duplicar_Item_clickHandler(event)"
				  enabled="{productGrid.selectedIndex != -1}"/>

	<mx:DataGrid id="productGrid" dataProvider="{ItemList}" 
				 editable="true" dragEnabled="true" dragMoveEnabled="true" 
				 dropEnabled="true" horizontalScrollPolicy="{ScrollPolicy.AUTO}"
				 width="100%"
				 height="100%"  />
