Using a class to create stacklayout more than once shows as a blank page.

Hi All,
I use a class to create StackLayout as given below ( Code to create Stacklayout ). The problem I'm facing is that I can't use this class twice to create the StackLayout using same class.
For example if I navigate from pages A --> B --> C --> D -- > A . When I use page A for first time I can add the stacklayout, but when I navigate second time to page A It shows as blank page.

Add Stacklayout to Page A

      StackLayout  content = new StackLayout ();
      LandscapeViewCreator creator = new LandscapeViewCreator ();
      await creator.SetCurrentView ();
      content .Children.Clear ();
      content .Children.Add (creator.CurrentView );

Code to create Stacklayout:

      public class LandscapeViewCreator:StackLayout
       {
       public StackLayout CurrentView { get; set; }

       public LandscapeViewCreator()
    {
    }

        async public void SetCurrentView ()
        {
          //Create StackLayout and Set it to CurrentView
        StackLayout CurrentView  = new StackLayout ();

        Label label = new Label ();
        label .BackgroundColor = Color.Black;
        label .Text = "Land";
        label .TextColor = Color.White;
        CurrentView.Children.Add (label );
       }
     }

I have tried removing Stacklayout from it's parent but It's not working. What could be the problem?? and how can I make it right. Thanks In advance..
