private var _myResults:ArrayCollection = new ArrayCollection();

private function resultsHandler(results:Object):void
{
    _myResults.removeAll();

    for(loop through results) {
        _myResults.addItem(result);
    }
}

You would then only need to set the data provider one time in your other
class, don't need to set it every single time the drop down changes.
