ActionScript 2.0 :: Keeping The Data Parameter Of The Object Created With A While Loop

i've been struggling with the following:

i am creating a list of buttons with an attachMovie. the AS is :

//as
var i = -1;
while(++i<userlist.length){
var user = userlist[i];

[Code].....

okay the problem is this: then i assign an on click function to every button right in the while loop that uses the data parameter of the "ob" object and when i play the movie the data parameter is always the parameter of the last object created for all the buttons. I know why this is happening- it overWrites the old "ob" with the new with every itteration of the loop.

But how would i go differently about creating an individual "ob" for each button created and still be able to have a function with a data parameter like this.onRelease.userClicked(data)?
