Change button style with VisualStateManager

Question

I am working on a Universal Windows App.

I want to change the Style of my button under different states but I cant figure out (I'm new to this)

Here is my visual state group

<VisualStateGroup x:Name="StartStopTimer">
    <VisualState x:Name="Start">
    </VisualState>
    <VisualState x:Name="Stop">
        <VisualState.Setters>
        </VisualState.Setters>
    </VisualState>
</VisualStateGroup>

I have two styles setup called StartButtonStyle and StopButtonStyle.

So I want to change the buttons style to StopButonStyle in the Stop visual state and StartButtonStyle in the Start visual state.

How do I do this? I tried with record on in Expression Blend but it doesn't apply anything to my visual state.

Here you are:

<VisualStateManager.VisualStateGroups>
        <VisualStateGroup x:Name="StartStopTimer">
            <VisualState x:Name="Start">
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="TestButton"
                                                   Storyboard.TargetProperty="Style">
                        <DiscreteObjectKeyFrame KeyTime="0" Value="{StaticResource StartButtonStyle}">
                        </DiscreteObjectKeyFrame>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </VisualState>
            <VisualState x:Name="Stop">
                <Storyboard>
                    <ObjectAnimationUsingKeyFrames Storyboard.TargetName="TestButton"
                                                   Storyboard.TargetProperty="Style">
                        <DiscreteObjectKeyFrame KeyTime="0"
                                                Value="{StaticResource StopButtonStyle}">
                        </DiscreteObjectKeyFrame>
                    </ObjectAnimationUsingKeyFrames>
                </Storyboard>
            </VisualState>
        </VisualStateGroup>
    </VisualStateManager.VisualStateGroups>

Of course you need to have defined your styles in the resources, for example in page resources.
