Question : Command:Click:Command is working fine for Button but its not working for Hyperlink

Commands:Click.Command is working fine for button but its not working when I do the same thing for hyperlink.My goal is when the user click on button or hyperlink I need to close the menu popup Its work fine for button but its not actually invoking the click command for hyperlink.We are using MVVM pattern for doing this.
//Button
<Button Grid.Row="0"
              Style="{StaticResource MenuItemButton}"
              Padding="4,3,3,3"
              Commands:Click.Command="{Binding ListLayoutCommand}"
              Commands:Click.CommandParameter="Vertical">

//Hyperlink
<HyperlinkButton Style="{StaticResource MenuItemLinkButton}"
                           Padding="32,3,3,3"
                           Commands:Click.CommandParameter="null"
                           Commands:Click.Command="{Binding CloseMenuCommand}"
                           ToolTipService.ToolTip="{Binding Description}"
                           Content="{Binding Name}"
                           NavigateUri="{Binding Value}"
                           TargetName="_blank">
           <Grid>
            <Grid.ColumnDefinitions>
             <ColumnDefinition Width="Auto"/>
             <ColumnDefinition Width="*"/>
            </Grid.ColumnDefinitions>
            <Canvas Height="16" Width="16" Grid.Column="0">
             <!-- TODO: replaces this canvas placeholder with an appropriate icon -->
            </Canvas>
            <TextBlock Grid.Column="1" VerticalAlignment="Center" Text="{Binding Name}" Margin="10,0,0,0"/>
           </Grid>
          </HyperlinkButton>


//This code is working fine its actaully gets invoked when the user click on the button
  public ICommand TileLayoutCommand
        {
            get;
            private set;
        }
 //This is were we are appending with DelegateCommand in the constructor
this.TileLayoutCommand = new DelegateCommand<string>( this.OnLayoutClick );

//When the user clicks on button we are invoking

  private void OnLayoutClick( string parameter )
        {
            var orientation = (Orientation) System.Enum.Parse( typeof( Orientation ), parameter, false );
            this.layoutManager.ApplyLayout( orientation );
            MenuService.CloseMenu();
        }

But I have done the same think for  hyperlink which is not working.

 /// <value>An <see cref="ICommand"/> object.</value>
        public ICommand CloseMenuCommand
        {
            get;
            private set;
        }

This is the property which is not getting triggered when the user clicks on the hyperlink.

 this.CloseMenuCommand = new DelegateCommand<object>( p => Microsoft.Advertising.Controls.MenuService.CloseMenu() );

Do I need to do some thing for invoking this method for the hyperlink.Could any one please help me out with this issue.

</HyperlinkButton> , end tag is in wrong place. Try placing it top of <Grid> tag
