Wanted: better code to dispatch custom event from mouse click

programming flash
1

Is there a better way of doing this?

var b:someButton = new someButton();
b.addEventListener(MouseEvent.CLICK, dispatchEvent, false, 0, true);

function dispatchEvent(e:MouseEvent):void
{
     dispatchEvent(new Event('SomeEvent',true));
}

I feel I should be able to remove the function and just have the click dispatch my custom event? Is this possible?

Thank you for your consideration,
S.
