你能描述一下我的WPF项目中有什么不正确的地方吗&

我是WPF的新手。这是我为MainWindow编写的代码

<StackPanel Grid.Row="1">

                <RadioButton Content="Главная"
                             Height="50"
                             Foreground="White"
                             FontSize="14"
                             Style="{StaticResource MenuButtonTheme}"
                             IsChecked="True"
                             Command="{Binding ChangeToHome}"/>

                <RadioButton Content="Добавить раскраску"
                             Height="50"
                             Foreground="White"
                             FontSize="14"
                             Style="{StaticResource MenuButtonTheme}"
                             Command="{Binding ChangeToDiscovery}"/>
</StackPanel>

以及MainViewModel.cs的此代码

private void ChangeToHome (object value)
{
    CurrentView = HomeVM;
    MessageBox.Show("Now in home", "alert", MessageBoxButton.OK, MessageBoxImage.Information);
}

private void ChangeToDiscovery (object value)
{
    CurrentView = DiscoveryVM;
    MessageBox.Show("Now in Discovery", "alert", MessageBoxButton.OK, MessageBoxImage.Information);
}

private bool CanChangeView(object value)
{
    return true;
}


public MainViewModel() 
{
    HomeVM = new HomeViewModel();
    DiscoveryVM = new DiscoveryViewModel();
    CurrentView = HomeVM;

    HomeViewCommand = new RelayCommand(ChangeToHome, CanChangeView);

    DiscoveryViewCommand = new RelayCommand(ChangeToDiscovery, CanChangeView);
}

我没有任何错误,但什么都不起作用。当我点击单选按钮时,没有消息,也不会改变视图。
