Javascript Control Addin Click Events doesent work

Hey there,
a few days ago i posted this: http://forum.mibuso.com/discussion/68810/customized-gantt-chart-in-nav-2016#latest .
The solution ig got from that work like a charm.

The only thing i struggle with are the click events in the NAV-Page.
When i test my Control Addin in a simple HTML-Page the click events and the scroll events work.
But when i integrate the addin into NAV, only the scroll even(zoom in my diagram) works.

Does anyone know why my View in the NAV-Page doesent delegate the click events?

Thanks in advance
