Custom DependencyProperty on Style.Trigger

for an UserControl I declared a DependencyProperty :

        public static readonly DependencyProperty DeselectedPresentationModeProperty =
        DependencyProperty.Register(
        "DeselectedPresentationMode",
        typeof(int),
        typeof(MyUserControl),
        new FrameworkPropertyMetadata(1,FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));

    public static readonly DependencyProperty SelectedPresentationModeProperty =
        DependencyProperty.Register(
        "SelectedPresentationMode",
        typeof(int),
        typeof(MyUserControl),
        new FrameworkPropertyMetadata(1, FrameworkPropertyMetadataOptions.AffectsRender | FrameworkPropertyMetadataOptions.BindsTwoWayByDefault));

Now I want to use these properties within a MultiTrigger:

    <Style TargetType="{x:Type ListBoxItem}" BasedOn="{StaticResource {x:Type ListBoxItem}}" x:Key="MyUserControlItemStyle">
        <Style.Triggers>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="IsSelected" Value="False" />
                    <Condition Property="gui:MyUserControl.DeselectedPresentationMode" Value="0" />
                </MultiTrigger.Conditions>
                <MultiTrigger.Setters>
                    <Setter Property="ContentTemplate" Value="{StaticResource PresentationModeIconOnly}" />
                </MultiTrigger.Setters>
            </MultiTrigger>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="IsSelected" Value="False" />
                    <Condition Property="gui:MyUserControl.DeselectedPresentationMode" Value="1" />
                </MultiTrigger.Conditions>
                <MultiTrigger.Setters>
                    <Setter Property="ContentTemplate" Value="{StaticResource PresentationModeSimple}" />
                </MultiTrigger.Setters>
            </MultiTrigger>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="IsSelected" Value="True" />
                    <Condition Property="gui:MyUserControl.SelectedPresentationMode" Value="0" />
                </MultiTrigger.Conditions>
                <MultiTrigger.Setters>
                    <Setter Property="ContentTemplate" Value="{StaticResource PresentationModeExtended}" />
                </MultiTrigger.Setters>
            </MultiTrigger>
            <MultiTrigger>
                <MultiTrigger.Conditions>
                    <Condition Property="IsSelected" Value="True" />
                    <Condition Property="gui:MyUserControl.SelectedPresentationMode" Value="1" />
                </MultiTrigger.Conditions>
                <MultiTrigger.Setters>
                    <Setter Property="ContentTemplate" Value="{StaticResource PresentationModeIconOnly}" />
                </MultiTrigger.Setters>
            </MultiTrigger>
        </Style.Triggers>
    </Style>
    ...
    ...
    <ListBox ... ItemContainerStyle="{StaticResource MyUserControlItemStyle}"/>

But if I use MyUserControl another project, there is no reaction if I change my DependencyProperty. Whether I use xaml e.g:

<Window 
...
x:Class="WpfControlsTester.MainWindow" 
Title="MainWindow">
<Grid>
    <GUI:MyUserControl Name="test"/>
    <Slider Minimum="0" Maximum="1" Value="{Binding SelectedPresentationMode, ElementName=test}" />
    <Slider Minimum="0" Maximum="1" Value="{Binding DeselectedPresentationMode, ElementName=test}" />
</Grid>

or if I use any kind of manipulation the value like this.test.DeselectedPresentationMode = 0; on an event or smth else.

I used WPF Inspector to "debug" my Triggers, and both properties always had their default value (1). Where is my mistake or what should I add to update my triggers?

Edit : Changed false "MyControl to "MyUserControl"

You can try the MultiDatatrigger instead like this in order to get the property changes:

<Style.Triggers>
                <MultiDataTrigger>
                        <MultiDataTrigger.Conditions>
                        <Condition Binding="{Binding IsSelected, RelativeSource={RelativeSource Self}}" Value="False" />
                        <Condition Binding="{Binding DeselectedPresentationMode, RelativeSource={RelativeSource AncestorType={x:Type MyUserControl}}}" Value="0" />
                        </MultiDataTrigger.Conditions>
                            <MultiDataTrigger.Setters>
                        <Setter Property="ContentTemplate" Value="{StaticResource PresentationModeIconOnly}" />
                        </MultiDataTrigger.Setters>
                </MultiDataTrigger>
            </Style.Triggers>

Thanks
