Problem running function from mouseup

Hi All... i am trying to get something quite simple to work

I draw a rewctangle and then "On mouseUp" i run the code "test()"

Then in the stage/creationComplete i have this function

function test(){

    alert("hello");

}

Nothing seems to happen, im trying to do something a little more complex later on but for now all i want to do is be able to run functions from within Adobe Edge.

My understanding was that creationComplete is where i put functions that can be accessable from anywhere in my composition..

Thanks for looking!..

Justin.
