ListView.ItemTapped not working when GroupHeaderTemplate is set in custom renderer (WP8)

Hi everyone

Firstly, thank you very much for the greate work you do. Xamarin form is definitly the best approach for cross platform development I have seen yet!

I try to create an application with a grouped ListView where the HeaderTemplate is red and uses the whole width of the screen (in WP8).
It was not possible for me to do this in xamarin.forms so I decided to implement a custom renderer.
But when replacing the GroupHeaderTemplate with an own implementation from the global application resource dictionary of the app.xaml, the ItemTapped will no longer fire. Furthermore I noticed that the data binding is no longer working.

To demonstrate this, I tried the same thing with the LabelledSectionList example and madethe following modifications:

Defining a DataTemplate inside the App.xaml of the WP8 Project:

<DataTemplate x:Key="GroupHeaderTemplate">
            <Border Background="Red" Height="48">
                <TextBlock Text="{Binding Title}" Foreground="White" FontSize="32"/>
            </Border>
</DataTemplate>

Then I created a custom renderer for the ListView:

[assembly: ExportRenderer(typeof(ListView), typeof(MyListViewRenderer))]
namespace LabelledSections.WinPhone
{
    class MyListViewRenderer : ListViewRenderer
    {
        protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.ListView> e)
        {
            base.OnElementChanged(e);
            Control.Name = "MyListView";
            Control.GroupHeaderTemplate = Application.Current.Resources["GroupHeaderTemplate"] as System.Windows.DataTemplate;
        }
    }
}

As you can see in the screenshot, the DataTemplate is applied. But when I tap no on a listview item, the tap event will be no longer fired. Am I doing something wrong or is this a bug?

Furthermore the binding is no longer working.

Best Regards
