Binding from a DataTemplate?

Question

I am creating a Silverlight control and I am trying to customize the bindings for Header and Body ContentControls through their respective DataTemplates. I am not sure why, but it does not work (silently fails). My only assumption is that DataTemplates are StaticResources. Can anyone offer advice? The control has the following default template:

<Style TargetType="local:LayoutItem">
<Setter Property="Template">
    <Setter.Value>
        <ControlTemplate TargetType="local:LayoutItem">
            <StackPanel>
                <StackPanel.Resources>

                    <DataTemplate x:Key="DefaultHeaderTemplate">
                        <StackPanel>
                           <TextBlock Text="{Binding HeaderText}" FontSize="15"/>
                        </StackPanel>
                    </DataTemplate>

                    <DataTemplate x:Key="DefaultBodyTemplate">
                        <StackPanel>
                            <TextBlock Text="{Binding BodyText}" FontSize="12"/>
                        </StackPanel>
                    </DataTemplate>

                </StackPanel.Resources>

                <ContentControl x:Name="Header" 
                   ContentTemplate="{StaticResource DefaultHeaderTemplate}" />
                <ContentControl x:Name="Body" 
                   ContentTemplate="{StaticResource DefaultBodyTemplate}" />
            </StackPanel>
        </ControlTemplate>
   </Setter.Value>

 

Thanks!

Update

Actually, the following code does not work either, so my assumption about StaticResources might be wrong.

<ContentControl x:Name="Header">
<ContentControl.ContentTemplate>
    <DataTemplate x:Key="DefaultHeaderTemplate">
        <StackPanel>
            <TextBlock Text="{Binding HeaderText}" FontSize="15"  />
        </StackPanel>
    </DataTemplate>
</ContentControl.ContentTemplate>
</ContentControl>

            <StackPanel x:Name="LayoutRoot">

                    <DataTemplate x:Key="DefaultHeaderTemplate">
                        <StackPanel>
                            <TextBlock FontSize="50" Text="{Binding Path=HeaderText}" />

                    </DataTemplate>

                </StackPanel.Resources>

                <ContentControl x:Name="Header" Content="{Binding}" ContentTemplate="{StaticResource DefaultHeaderTemplate}" />

            </StackPanel>
        </ControlTemplate>
    </Setter.Value>
</Setter>

Content = "{Binding}". .:)

-.

/// ctor
public MyClass()
{
   this.DataContext = ObjectThatIsDataContext;
}

XAML:

<UserControl ...>
    <UserControl.Resources>
       <myNS:MyClass x:Name="TheContext" x:Key="TheContext" />    </UserControl.Resources>
    <Grid x:Name="LayoutRoot" Background="White" DataContext="{StaticResource TheContext}" >
        <TextBlock Text="{Binding Path=Field1}" />
    </Grid>
</UserControl>

(3 ):

        <ContentControl x:Name="Header">
            <ContentControl.ContentTemplate>
                <DataTemplate >
                    <StackPanel>
                        <TextBlock Text="{Binding HeaderText}" FontSize="15"  />
                    </StackPanel>
                </DataTemplate>
            </ContentControl.ContentTemplate>
            <ContentPresenter />
