Correct way to use an event handler

Question

The following is dynamically adds a series of buttons and a label to each button. The problem is that the event handler fires twice for each button, and the last button never gets processed at all.
Should I be using a different event handler than ResizeEvent.RESIZE? How do I add the label to the last button in the sequence?
Thank you.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
    <mx:Script>
  <![CDATA[
      import mx.events.ResizeEvent;
private var button:Button2;
public var numButtons:Number=5;
private var counter:Number=0;
public function init():void{
    for(var i:int=0; i<numButtons;i++){
        button=new Button2;
        hbox.addChild(button)
        button.addEventListener(ResizeEvent.RESIZE, handleButtonAdded)
private function handleButtonAdded(e:ResizeEvent):void{
    counter++
    trace(e.target)
    e.target.label= String(counter);
    button.removeEventListener(ResizeEvent.RESIZE, handleButtonAdded)
  ]]>
</mx:Script>
<mx:HBox id="hbox"  horizontalGap="0"/>
</mx:Application>
Here's the button: Button2.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Button xmlns:mx="http://www.adobe.com/2006/mxml" creationComplete="init()" >
<mx:Script>
    <![CDATA[
    public function init():void{
        this.width=100;
    ]]>
</mx:Script>
</mx:Button>

Hmm , what are you trying to do ?  There are a few questionable things happening.  Your event-handler is named "handleButtonAdded" but it takes a ResizeEvent ? Do you mean to trigger an event based on when the button was added to the stage , or parent such as FlexEvent.ADDED or when the creation is complete ,  FlexEvent.CREATION_COMPLETE ?
   The second thing is your "button" variable.  It is declared outside of the loop in the "init" function.  Meaning , when that loop is done and even during execution , it will point to the last button created.  So all the buttons have listeners , meaning when one button fires off a ResizeEvent , it will remove the listener for whatever your variable "button" is pointing to.  This guarantees (well , maybe not) the behaviour that your last button will NOT have a listener , therefore it will not fire.
  By the way , you can set the label and the size of the button when you declare them. You don't have to subclass and use listeners.
