sound not playing at the right moment

I created a MediaElement for a Background Music in my Windows Phone App and it plays perfectly now the problem when I tried to add sound for a button when pressed

When I debug , the Background music plays , but when I press the button it navigates me to the next page without playing the sound I created, and when I press BackButton from the Navigated Page , it plays it, why?

code:

private void play_Click(object sender, RoutedEventArgs e)
{
    MediaElement Click = new MediaElement();
    Click.Source = new Uri ("/Assets/Sounds/press.mp3",UriKind.Relative);
    Click.Position = TimeSpan.Zero;
    Click.Volume = 1;
    LayoutRoot.Children.Add(Click);
    Click.Play();
    NavigationService.Navigate(new Uri("/NavPage.xaml", UriKind.Relative));
}

private void play_Click(object sender, RoutedEventArgs e)
        {
            MediaElement Click = new MediaElement();
            Click.Source = new Uri ("/Assets/Sounds/press.mp3",UriKind.Relative);
            Click.Position = TimeSpan.Zero;
            Click.Volume = 1;
            LayoutRoot.Children.Add(Click);
            Click.Play();

        }

you should handle this outside button click,

NavigationService.Navigate(new Uri("/NavPage.xaml", UriKind.Relative));

Add an event handler to the click and call separately,

 Click.MediaEnded += Click_Completed;

 void Click_Completed(object sender, RoutedEventArgs e)
        {
           NavigationService.Navigate(new Uri("/NavPage.xaml", UriKind.Relative));
        }

---

or you can make MediaEnded event of the mediaElement and there in you can call the navigation

Like this:

private void play_Click(object sender, RoutedEventArgs e)
        {
            MediaElement Click = new MediaElement();
            Click.Source = new Uri ("/Assets/Sounds/press.mp3",UriKind.Relative);
            Click.Position = TimeSpan.Zero;
            Click.Volume = 1;
            LayoutRoot.Children.Add(Click);
            Click.MediaEnded += Click_MediaEnded;
            Click.Play();
        }

void Click_MediaEnded(object sender, RoutedEventArgs e)
       {
            NavigationService.Navigate(new Uri("/NavPage.xaml", UriKind.Relative));
       }
