OnOrientationEvent not fires

[Thiago]

Hi,
I´ve added a transition control, how the sample provided on documentation, to switching between pages.
But now, if I want use OnOrientationChanged event is not fired.
Below is the code:

private void InitializePhoneApplication()
        {
            if (phoneApplicationInitialized)
                return;

            // Create the frame but don't set it as RootVisual yet; this allows the splash
            // screen to remain active until the application is ready to render.
            RadTransition transition = new RadTransition();
            transition.BackwardInAnimation = this.Resources["fadeInAnimation"] as RadFadeAnimation;
            transition.BackwardOutAnimation = this.Resources["fadeOutAnimation"] as RadFadeAnimation;
            transition.ForwardInAnimation = this.Resources["fadeInAnimation"] as RadFadeAnimation;
            transition.ForwardOutAnimation = this.Resources["fadeOutAnimation"] as RadFadeAnimation;
            transition.PlayMode = TransitionPlayMode.Consecutively;

            RadPhoneApplicationFrame frame = new RadPhoneApplicationFrame();
            frame.Transition = transition;
            RootFrame = frame;
            RootFrame.Navigated += CompleteInitializePhoneApplication;
            // Handle navigation failures
            RootFrame.NavigationFailed += RootFrame_NavigationFailed;
            // Ensure we don't initialize again
            phoneApplicationInitialized = true;

        }

public partial class Gerador : PhoneApplicationPage
    {
        private GraficoViewModel ViewModel { get; set; }

        public Gerador()
        {
            ViewModel = new GraficoViewModel();
            DataContext = ViewModel;

            InitializeComponent();

            ViewModel.GeraGrafico(Utils.ALTURA_PORTRAIT, Utils.LARGURA_PORTRAIT, ref ContentPanel);
        }

        protected override void OnOrientationChanged(OrientationChangedEventArgs e)
        {
            base.OnOrientationChanged(e);

            //It´s not fired
        }
    }

Is there anything wrong?
Thanks in advance,
Thiago
