WPF Menu Item with Button

Question

How can I add a Button to the menu items shown in the image below? I've tried creating a MenuItem template but when i use that the Header text of the menu item no longer displays what Binding am I doing wrong here?

Not using menuitem template

Using Menu Item Template which is currently commented out in the code:

I would prefer it looks like this using a label as the text and a Button.

<Window.Resources>
    <XmlDataProvider x:Key="MockList"   XPath="/MockObjects/*" >
        <x:XData >
            <MockObjects xmlns="">
                <MockObject  Name="Louis" Type="A" Number="1" />
                <MockObject Name="Joseph Angelo" Type="A" Number="2" />
                <MockObject Name="Papineau Philadelphia" Type="B" Number="301" />
                <MockObject  Name="Mary" Type="B" Number="4" />
                <MockObject Name="Kevin" Type="C" Number="5" />
                <MockObject Name="Sarah" Type="D" Number="6" />
                <MockObject  Name="Doug" Type="E" Number="7" />
                <MockObject Name="Leslie" Type="F" Number="8" />
                <MockObject Name="Mike" Type="G" Number="9" />
                <MockObject Name="Sue" Type="H" Number="10" />
                <MockObject  Name="Michelle" Type="I" Number="11" />
                <MockObject Name="Ron" Type="J" Number="12" />
                <MockObject Name="Amy" Type="K" Number="13" />
            </MockObjects>
        </x:XData>
    </XmlDataProvider>
</Window.Resources>

<DockPanel>
    <Menu Grid.Row="0" BorderThickness="0,0,0,1">
        <MenuItem Header="_File">
            <MenuItem Header="Custom Presets" DataContext="{Binding Source={StaticResource MockList}}"  ItemsSource="{Binding Mode=Default, XPath=/MockObjects/MockObject}">
                <MenuItem.ItemContainerStyle>
                    <Style>
                        <Setter Property="MenuItem.Header" Value="{Binding XPath=@Name}"/>
                        <Setter Property="MenuItem.Command" Value="{Binding Open}"/>
                    </Style>
                </MenuItem.ItemContainerStyle>
                <!--<MenuItem.ItemTemplate>
                    <HierarchicalDataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <TextBlock Text="{Binding Header}"/>
                            <TextBlock Text="{Binding XPath=@Name}" Width="150" Foreground="Red"/>
                            <Button Content="X" Background="Firebrick" Cursor="Hand"/>
                        </StackPanel>
                    </HierarchicalDataTemplate>
                </MenuItem.ItemTemplate>-->
            </MenuItem>

        </MenuItem>
    </Menu>
</DockPanel>

The following ControlTemplate should work:

<Menu Grid.Row="0" BorderThickness="0,0,0,1">
    <MenuItem Header="_File">
        <MenuItem Header="Custom Presets" DataContext="{Binding Source={StaticResource MockList}}" 
                          ItemsSource="{Binding Mode=Default, XPath=/MockObjects/MockObject}">
            <MenuItem.ItemContainerStyle>
                <Style TargetType="MenuItem">
                    <Setter Property="MenuItem.Header" Value="{Binding XPath=@Name}"/>
                    <Setter Property="MenuItem.Command" Value="{Binding Open}"/>
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate TargetType="{x:Type MenuItem}">
                                <Border x:Name="templateRoot" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
