Any code clip of XAML and C++ for ToggleMenuFlyout data binding?

Question

The XAML clip is

<Button x:Name="btnNavigate" Style="{StaticResource RefreshAppBarButtonStyle}" AutomationProperties.Name="Loop" Click="NavigationButton_Click">
                        <Button.Flyout>
                            <MenuFlyout>
                                <ToggleMenuFlyoutItem Text="Shuffle" Tag="shuffle" IsChecked="{Binding IsShuffleEnabled, Mode=TwoWay}" Click="NavigationMenuFlyout_Click" />
                                <ToggleMenuFlyoutItem Text="Repeat" Tag="repeat" IsChecked="{Binding IsRepeatEnabled, Mode=TwoWay}" Click="NavigationMenuFlyout_Click" />
                            </MenuFlyout>
                        </Button.Flyout>                    
</Button>

How can I bind IsShuffleEnabled and IsRepeatEnabled variables in C++?

I do not understand how to use INotifyPropertyChanged method and there is no C++ example.
