MenuItem and IcollectionView

Question

I want to display a list of available languages in a menu. The languages are available as an ICollectionView.

This is the code:

<Menu DockPanel.Dock="Top">
 <Menu.Resources>
  <Style x:Key="LanguageMenuStyle" TargetType="MenuItem">
   <Setter Property="Header" Value="{Binding Name}"></Setter>
   <Setter Property="IsCheckable" Value="True"/>
  </Style>
 </Menu.Resources>
 <MenuItem Header="Language" ItemsSource="{Binding Languages}"
              ItemContainerStyle="{StaticResource LanguageMenuStyle}">
 </MenuItem>
</Menu>

Languages is an ICollectionView created as default view from a list of cultures. The menu is displayed correctly. Now I would like to bind to the CurrentChanged event when the selection in the menu changes, but since there is no IsSynchronizedWithCurrentItem property, how could I do that?

And is there a way to allow only one item to be checked at a time?
