Inject Code Behind Element Into XAML Data Template

As the title suggests I'm looking to inject a code behind element into a data template to be rendered at runtime.

Here is the piece of my XAML code I'd like to inject the code behind element into:

<TabControl x:Name="tcDocuments" DockPanel.Dock="Top">
    <TabControl.ItemTemplate>
        <DataTemplate>
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{Binding Name}" />
                <Button Content="x" />
            </StackPanel>
        </DataTemplate>
   </TabControl.ItemTemplate>
   <TabControl.ContentTemplate>
       <DataTemplate>
           (INSERT CLASS BELOW'S CONTENT PROPERTY HERE)
       </DataTemplate>
   </TabControl.ContentTemplate>
</TabControl>

And here is the class that I will be adding to the TabControl above's Items:

public class DocumentTab
{
    public string File { get; set; }
    public string Name { get; set; }
    public RichTextBox Content { get; set; }
}

Then every time I add a new DocumentTab object to the TabControl's Item list, The RichTextBox property "Content" is inserted into the DataTemplate tag.

I guess the real question here is is this possible?

Cheers.
