Mouse events on the timeline

Hello.

I could paste events with html tags and add some event listeners for this html elements. But now when I tried to add event listeners to icon on the timeline (for example:" $(document).on('click', '.myClass',function); "), this would not work. In firefox I can add "mouseup" and "mousedown" events, but in IE 10 it will not work. I have tried to use "clickToUse" option. I thought that it would enable mouse events on the timeline area, but it didn't work.

Thank You.
