There are a few ways to do this but the easiest is to add a value to your
object that will be updated in the item renderer, perhaps in the set data
function. You could also use an event and a public property in your item
renderer.
var myObject = new myClass();
override public function set data(value:Object):void
{
//value is the object from your list
myObject = value as MyClass;
}
private function buttonClick()
{
myObject.randomNumber = MyRandomNumberGen();
}
You should now be able to access randomNumber in your application.
This will require you to parse your ArrayCollection into an object.
