DOUBLE_CLICK dont work in actionscript3

I have

MyMovie.addEventListener(MouseEvent.CLICK, goClick)
function goCl开发者_JAVA技巧ick(e:MouseEvent):void
{
trace("Trololo");
}

It's work.

Why don't work?

MyMovie.addEventListener(MouseEvent.DOUBLE_CLICK, goDouble)
function goDouble(e:MouseEvent):void
{
trace("Trololo");
}

You have to set doubleClickEnabled to true.

MyMovie.doubleClickEnabled = true;
