Retrieve the current index from a Event in a Repeater

Question

I'm using a Repeater to display several Button dynamically and need to pass the index of the clicked button to the clickHandler:
<mx:Repeater id="r" dataProvider="{aAC}" startingIndex="0">
     <mx:Button id="btn" height="15" fontSize="9" label="Click It" click="clickHandler(event.currentTarget.getRepeaterItem().currentIndex);"/>
</mx:Repeater>
aAC is an ArrayCollection. The index should be the index of aAC.
I also tried "r.currentIndex", "event.target.index", .... None of them worked. What parameter should I use in the clickHandler?
Thanks.

This code might be adaptable for your purposes:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
  <mx:Script>
    <![CDATA[
      import mx.collections.ArrayCollection;
      import mx.controls.Alert;
      [Bindable] private var aAC:ArrayCollection = new ArrayCollection([
        "item one", "item two", "item three", "item four", "item five"
      private function clickHandler(evt:MouseEvent):void{
        Alert.show(aAC.getItemAt(evt.currentTarget.name).toString());
    ]]>
  </mx:Script>
  <mx:Repeater id="r" dataProvider="{aAC}" startingIndex="0">
    <mx:Button id="btn" height="15" fontSize="9" label="Click It"
      click="clickHandler(event);" name="{r.currentIndex}"/>
  </mx:Repeater>
</mx:Application>
