You will want to override the set data method of the item renderer:

<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/halo">
    <fx:Script>
     <![CDATA[

      //Strongly typed VO for use in binding.
      [Bindable]
      private var myValueObject:MyValueObject;

      override public function set data(value:Object) : void
      {
       //we don't want to update if the value is the exact same.
       if(data === value)
        return;

       //you could simply access the data property but I think
       //it is nicer to have strong typing for code hints
       super.data = myValueObject = value;
       validateNow();
      }
     ]]>
    </fx:Script>
    <mx:Label text="{myValueObject.name}"/>
</mx:Canvas>
