WPF Itemscontrol datatemplate property changing

Question

I'm currently using the following itemscontrol and datatemplate:

<UserControl.Resources>
    <DataTemplate x:Key="OrdersTemplate">
        <dxlc:LayoutItem Label="CustomerReference" LabelPosition="Top" MaxWidth="300" HorizontalAlignment="Left" Width="300">
            <dxe:TextEdit IsEnabled="True" Text="{Binding Path=CustomerReference}" />
        </dxlc:LayoutItem>
    </DataTemplate>
</UserControl.Resources>

<HeaderedContentControl Header="Steps">
    <ItemsControl ItemsSource="{Binding Orders}" ItemTemplate="{StaticResource OrdersTemplate}"/>
</HeaderedContentControl>

The source is just a list with entities.

The problem is that the "CustomerReference" of every object from my source changes when I change it in the textbox. Whats missing here?
