I've done that but still not work.. the play head dos not move ..

When I add

alert(this);

inside function myFunction() .. I get [Object window ] message..

The question still How Can I refer to the timeline to play the play head??

Event handlers default to executing in the global window context. Yes, this was a very poorly thought out design decision, but now we're stuck with it.

To force a function to execute in a specific context, you have to use .bind() on it.

Function.prototype.bind() - JavaScript | MDN

A little correctness:this.play(pos+1); instead of this.stop(pos+1);
