UPDATE:
Based on your comments, this should be even easier. You would just loop through each of the rows in your List's dataProvider and make whatever changes are necessary. At the end of the function just call the refresh function on the ArrayCollection. Using my example below:
public function myFunction(evt:Event):void
{
for each (var o:MyObject in myDataProvider)
{
o.someProperty = "Updated";
}
myArrayCollection.refresh();
}
After the ArrayCollection is updated, calling the refresh function should cause the List to refresh its item renderers as well.
ORIGINAL ANSWER:
It sounds like you want to call a function outside your ItemRenderer when a button or something is clicked in the ItemRenderer but still be able to access the data for the item that was clicked.
Assuming I've got this correct, you still wouldn't need to access the ItemRenderer itself. You can just do something like this (just a rough example):
<fx:Script>
<![CDATA[
public function myFunction(evt:Event):void
{
trace(MyObject(myList.selectedItem).someProperty.toString());
}
]]>
</fx:Script>
<mx:List id="myList" dataProvider="{myDataProvider}" >
<mx:itemRenderer>
<fx:Component>
<mx:CheckBox selectedField="IsSelected" change="outerDocument.myFunction(event);" />
</fx:Component>
</mx:itemRenderer>
</mx:List>
If you do need to pass a completely separate parameter that's not stored in your List's dataProvider, just pass it as an argument to the change eventHandler.
change="outerDocument.myFunction(event, someOtherValue);"
