<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()">
     <mx:Script>
          <![CDATA[
               import mx.collections.ArrayCollection;
               import mx.events.CollectionEvent;
               [Bindable]
               public var expenses:ArrayCollection = new ArrayCollection([
                    {Month:"Jan", Profit:2000, Expenses:120, Amount:45},
                    {Month:"Feb", Profit:1000, Expenses:200, Amount:60},
                    {Month:"Mar", Profit:1500, Expenses:500, Amount:30}
               public var myArray:Array=[{Month:"Mar", Profit:1500, Expenses:500, Amount:30}];
               private function init():void{
                    expenses.addEventListener(CollectionEvent.COLLECTION_CHANGE,myFunction);
               private function myFunction(e:CollectionEvent):void{
                    trace("I was changed");
