WPF Databinding TabItem Headers

Question

I am binding a ObservableCollection of data objects to my tab control item source. I have correctly figured out how to bind the controls within the tabitem that is generated, however I cannot figure out how to change the header property of the tabitem that is generated using the a property within the Observable Collection. Sorry if I am wording this incorrectly. Here is my XAML for the tabitem data template:

<DataTemplate x:Key="TabItemTemplate">
        <TreeView Height="461" VerticalAlignment="Top" 
            Width="625" ItemTemplateSelector="{StaticResource TreeviewDataSelector}" ItemsSource="{Binding}" />
</DataTemplate>

Create a Style for your TabItems that sets the Header property, and apply the style to TabControl.ItemContainerStyle

<TabControl>
    <TabControl.ItemContainerStyle>
        <Style TargetType="TabItem">
            <Setter Property="Header" Value="{Binding PathToYourProperty}"/>
        </Style>
    </TabControl.ItemContainerStyle>
</TabControl>

Set the DisplayMemberPath on the TabControl to the name of the property.

<TabControl ItemsSource="{Binding items}" DisplayMemberPath="headerPropertyName">

I had to use this with Caliburn and convention binding: <TabControl x:Name="SectionViewModels" DisplayMemberPath="HeaderText" />
