I got a question about changing the background image of a button when it's clicked.

I tried searching on google but i couldn't find something that worked for me.

Well here's my code

<Button Grid.Column="0" Grid.Row="0" x:Name="btnHome" VerticalAlignment="Stretch" BorderBrush="{x:Null}" HorizontalAlignment="Stretch" Click="btnHome_Click" PointerEntered="btnHome_PointerEntered">
                <Button.Template>
                    <ControlTemplate TargetType="Button">
                        <Border x:Name="RootElement">
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="MouseOver">
                                        <Storyboard>
                                            //I want my background change here
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="Pressed">
                                        <Storyboard>
                                            //And here
                                        </Storyboard>
                                    </VisualState>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                            <Border.Background>
                                <ImageBrush ImageSource="images/back_button.png"/>
                            </Border.Background>
                        </Border>
                    </ControlTemplate>
                </Button.Template>
            </Button>

i also tried this

private void btnHome_PointerEntered(object sender, PointerRoutedEventArgs e)
    {
        BitmapImage bmp = new BitmapImage();
        Uri u = new Uri("ms-appx:images/back_button_mouseover.png", UriKind.RelativeOrAbsolute);
        bmp.UriSource = u;
        ImageBrush i = new ImageBrush();
        i.ImageSource = bmp;
        btnHome.Background = i;
    }

But unfortunately this worked neither
