怎么引用Repeater下控件属性

如何引用Repeater下控件属性
代码先贴出来
<mx:Repeater id="pp" dataProvider="{myData.row}">
  <mx:Button height="90" width="89" label="{(pp.currentItem.Name)}"/>
   
  </mx:Repeater>  
其中myData 是通过HTTPService回调函数里返回的Object,
[Bindable]
public var myData:Object;  
public function shopHandler(event:ResultEvent):void
{
myData=event.result.shop;
}
现在想要引用Button中的label的值，怎么引用

是不是这个意思？你点击按钮的时候，不知道当前按钮应该对应dataProvider中的哪条记录，也就是不知道下标是什么

XML code

<?xml version="1.0" encoding="utf-8"?> 
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:local="*">
<mx:Script>
    <![CDATA[
        import mx.controls.Button;
        import mx.controls.Alert;
        private function onClickHandler(event:Event):void
        {
            var myButton:MyButton = event.target as MyButton;
            if (myButton != null) {
                // 从按钮中获得dataProvider所对应的下标，即可以获得dataProvider中按钮对应的相关信息。
                var currentIndex:int = myButton.index;
                Alert.show(pp.dataProvider[currentIndex]);
            }
        }
    ]]>
</mx:Script>
    <mx:Repeater id="pp" dataProvider="{[1,2,3,4,5]}">
        <!-- 通过index="{pp.currentIndex}" 把当前Repeater的下标传入按钮中 -->
        <local:MyButton height="90" width="89" label="{pp.currentItem}" index="{pp.currentIndex}" click="onClickHandler(event)"/>
    </mx:Repeater> 
 
</mx:Application>
