dhtmlxscheduler with durandal issue

I am using dhtmlxscheduler with durandal. As my scheduler page renders for the first time, when I drag my events it move up in scheduler timeline for a day, but as I reload the page, it works OK. When I navigate to other page and return to my scheduler page again, it again move up during drag but after reloading the page it works ok. Can I get help what is going wrong which is making scheduler drag , move work within line but when I just navigate b/w pages it doesn’t work

please give a link to some kind of demo or problematic page, so somebody could test the issue
