Try these things for I believe its a binding issue:

1. Debug and put a breakpoint in the GoogleView constructor and verify
   it is being instantiated.
2. If it is being instantiated verify the data you are binding to exists within the class.
3. If everything instantiated, try binding to the collection as TwoWay binding mode.
4. If that doesn’t work try binding to the data in another control to verify things are working properly.
