i fixed it by this in C# code

 DispatcherPriority.Background,
                    new Action(() => ((MainWindow)System.Windows.Application.Current.MainWindow).answerCall.Visibility = Visibility.Visible));

If you use a controller/viewmodel, you shouldn't have any code behind, instead of that, you should work with bindable properties and commands, implementing INotifyPropertyChanged interface, in some base class if you want.
