Usercontrol Binding not working

Question

Hello,

I created a UserControll (RadialTick), add some dependency properties to it, and added Binding in its associates xaml file that use those properties.
When I want to use my usercontrol in a normal window(Windows2), the value that I supply do not get propagated to the bound components in the usercontrol.
I have tried to find out why but have been unsuccessfull.

If you are wandering what I am doing, I am building gauge like components for dashboard.

Any help would greatly be appreciated!

Kind Regard,
Nick.
