WPF Context menu doesn't bind to right databound item

Question

I have a problem when binding a command in a context menu on a usercontrol that is on a tab page. The first time I use the menu (right-click on the tab) it works great, but

I prefer another solution. Add context menu loader event.

<ContextMenu Loaded="ContextMenu_Loaded"> 
    <MenuItem Header="Change" Command="{Binding Path=ChangeCommand}"/> 
</ContextMenu> 

Assign data context within the event.

private void ContextMenu_Loaded(object sender, RoutedEventArgs e)
{
    (sender as ContextMenu).DataContext = this; //assignment can be replaced with desired data context
}
