[Tweener] Using passing variables through event listeners to trigger correct tween

[Baluta Cristian]

i'm not shure you can send arguments like that, and the code is ugly also.
two solutions:
1. i hope your buttons are classes. add events inside the class, the button
2. use custom events but is much more complicated because you have to pass
the "i" to the class, then dispatch the events with that "i". and you also
need to add the custom event from outside the button.
