Use event function for multiple events

Question

I've got several movieclip buttons on stage. For one of those buttons I've started of with:
button1.buttonMode = true;
button1.useHandCursor = true;
button1.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
          button1.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
function fl_ReleaseToDrop(event:MouseEvent):void
          button1.stopDrag();
Which works. But I would like to have that fl_ClickToDrag function excuted for all my other buttons too, so I don't have to duplicate that several times for each button. So I thought I use something like:
button1.buttonMode = true;
button1.useHandCursor = true;
button2.buttonMode = true;
button2.useHandCursor = true;
button1.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
button2.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
  event.target.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
function fl_ReleaseToDrop(event:MouseEvent):void
  event.target.stopDrag();
But that gives an error. What's the correct way?

Actually I got it working by using:
button1.buttonMode = true;
button1.useHandCursor = true;
button2.buttonMode = true;
button2.useHandCursor = true;
button1.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
button2.addEventListener(MouseEvent.MOUSE_DOWN, fl_ClickToDrag);
function fl_ClickToDrag(event:MouseEvent):void
  event.currentTarget.startDrag();
stage.addEventListener(MouseEvent.MOUSE_UP, fl_ReleaseToDrop);
function fl_ReleaseToDrop(event:MouseEvent):void
  stopDrag();
