Animator addon not working..

Hi guys,
I am using Animator addon v2. I put the following code in my UI.

Button button = new Button(“Click Me”);
button.addClickListener(new Button.ClickListener() {
public void buttonClick(ClickEvent event) {
Label label = new Label(“Thank you for clicking”);
Animator.animate(label, new Css().opacity(0.5));
Animator.animate(label, new Css().translateX(“100px”)).delay(1000).duration(2000);

I wanted some animation to take place and nothing happened except the label with ‘Thank you for clicking’ showed up! Is the addon a total failure? Please help?
