tweening a button

[Gods]

I am not familiar with tween but I am trying to tween a button when its clicked 
http://jsfiddle.net/rxdrvquo/

When I click it the tween works but the button doesnt work? 

I am not sure if I am doing it the best way either as I want all my buttons to have this tween effect. lmk thanks

My guess is that you are not passing a callback context to this line:

this.button.events.onInputDown.add(this.clicked);

Try it like this and see how it goes:

this.button.events.onInputDown.add(this.clicked, this);

I tried passing the callback context and still doesnt work.
