Databinding to controledTemplate and contentPage

Hi, I have created controlled template to which I bind some properties. Then I have Main view which Is a page to which I need to bind one class to render realtime data.

Problem is that when I use bindablecontext=myclass; IT breaks the other databinding which goes to template.

Here is the code
