Bind to single object in viewmodel

I got this property in my viewmodel:

        private PushPinModel selectedPushPinModel;
    public PushPinModel SelectedPushPinModel
    {
        get { return selectedPushPinModel; }
        set
        {
            selectedPushPinModel = value;
            RaisePropertyChanged(() => SelectedPushPinModel);
        }
    }

And I want to bind the view to show which one is selected:

        <ContentControl DataContext="{Binding SelectedPushPinModel}" VerticalAlignment="Top">
        <ContentControl.ContentTemplate>
            <DataTemplate>
                <Grid Height="100" VerticalAlignment="Top">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="20*"/>
                        <RowDefinition Height="38*"/>
                    </Grid.RowDefinitions>
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="91*"/>
                        <ColumnDefinition Width="389*"/>
                    </Grid.ColumnDefinitions>
                    <Border Opacity="0.95" Width="480" Padding="0,0,0,0" BorderThickness="0" HorizontalAlignment="Left" BorderBrush="Transparent" Background="White" Grid.ColumnSpan="2" Grid.RowSpan="2"/>
                    <Image Width="70" Height="70" HorizontalAlignment="Center" VerticalAlignment="Center" Source="{Binding Icon}" Grid.Column="0" Grid.Row="0" Grid.RowSpan="2" />
                    <TextBlock Text="{Binding Header}" Grid.Column="1" Grid.Row="0" Style="{StaticResource TextboxLabelStyle}"/>
                    <TextBlock Text="{Binding Body}" Grid.Column="1" Grid.Row="1" Style="{StaticResource DefaultTextBlockStyle}"/>
                </Grid>
            </DataTemplate>
        </ContentControl.ContentTemplate>
    </ContentControl >

However I can't get it to work. The bindings is not showing in the view and I'm not getting any binding errors. Is it the correct way to bind to a single object? I much rather having it like this instead of binding directly with {Binding SelectedPushPinModel.Body} which more dirty.

Any suggestions how to accomplish this? Thanks

Solved it, replaced DataContext on the ContentControl with Content

<ContentControl Content="{Binding SelectedPushPinModel}" VerticalAlignment="Top">

Thanks to sircodesalot for pointing me to the right direction!

Try this: 

<Label Content="{Binding SelectedPushPinModel}" />

See what that gives you (if anything). Also, check the 'output' window for errors.

This line:

<ContentControl DataContext="{Binding SelectedPushPinModel}">

will only work if the DataContext for the ViewModel (Class) has been properly bound higher on the page. If it isn't then the Label binding provided above will show blank.
