Combine "apply buffer" & interesct function on Spatial Search - eSearch Widget

I try to combine apply buffer button with intersect button so the user only need to click one time then able to draw buffer ring and show all the results interest with the buffer ring. Here is what I did:
private function sOpBtnClickHandler(event:Event):void
{
applyBuffer(); //Apply buffer ring
intersectResults(event.currentTarget.name);
}

But no luck!. Only shows interesect results.

Thank you.
