WP7 Updating Pivot control title - data-binding

Question

I have a Pivot control which I am using as following within the XAML.
I have bound the Pivot Title to a method on my view model as its content will vary depending upon what is being displayed.
<controls:Pivot x:Name="MainPivot" ItemsSource="{Binding PivotItemHeaders}" Title="{Binding ApplicationTitle}" >
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding Description}"/>
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<ListBox x:Name="EventsListbox"
ItemsSource="{Binding allEventItems}"
ItemTemplate="{StaticResource EventDisplay3}"
SelectionChanged="EventsListbox_SelectionChanged"/>
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
The collection of items is being refreshed and the binding is working fine for these objects - however the Pivot title is not refreshing with the new value.
It seems stuck at the value when the page/pivot control was first shown.
Any ideas how I can get the pivot control to refresh? - Thanks

I just did a quick test, binding works just fine:
<controls:Pivot Title="MY APPLICATION" ItemsSource="{Binding Items}">
<controls:Pivot.HeaderTemplate>
<DataTemplate>
<TextBlock Text="{Binding LineOne}" />
</DataTemplate>
</controls:Pivot.HeaderTemplate>
<controls:Pivot.ItemTemplate>
<DataTemplate>
<Grid>
<Button Content="Update" Click="Button_Click" />
</Grid>
</DataTemplate>
</controls:Pivot.ItemTemplate>
</controls:Pivot>
And in the C#
private void Button_Click(object sender, RoutedEventArgs e)
{
App.ViewModel.Items.Clear();
App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "foo" });
App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "bar" });
App.ViewModel.Items.Add(new ItemViewModel() { LineOne = "baz" });
}
So clearly you're doing something very wrong. Post your code and we'll take a look.
Update
Title Binding also works
XAML
<controls:Pivot Title="{Binding Title}">
<controls:PivotItem Header="first">
<Grid>
<Button Click="Button_Click" Content="OK!" />
</Grid>
</controls:PivotItem>
</controls:Pivot>
C#:
private void Button_Click(object sender, RoutedEventArgs e)
{
Title = "foobar!";
PropertyChanged(this, new PropertyChangedEventArgs("Title"));
}
