title: Dependency property null
body: <p>I have created my UserControl with <code>Owner</code> property</p>
  
  <pre><code>&lt;shared:NavigationControl Owner="{Binding  ElementName=This, Converter={StaticResource TestConverter}}"  /&gt;
  </code></pre>
  
  <p><code>This</code> property is <code>x:Name</code> of my Page.</p>
  
  <p>Here is code behind: </p>
  
  <pre><code>public MvxWindowsPage Owner
  {
      get { return (MvxWindowsPage)GetValue(OwnerProperty); }
      set { SetValue(OwnerProperty, value); }
  }
  
  public static readonly DependencyProperty OwnerProperty =
                DependencyProperty.Register("Owner", typeof(MvxWindowsPage), typeof(NavigationControl), null);
  </code></pre>
  
  <p>I have created <code>TestConverter</code> to check if binding is ok and it is.</p>
  
  <p>Why <code>Owner</code> property is <code>null</code> in cs?</p>
