How to reset a tween?

[neonwarge04]

Is there a way to reset a tween?  I have a tween which animates the object to move upward from the bottom-most of the screen. Now if I selected the object, it will collapse back to where it came from. I am able to animate the object to show to the screen but I can't animate it back.

I sneaked into the source but couldn't found a way. Any ideas? This is frustrating, it feels like I am coding in assembly. 

Thanks!

I am so sorry, I forgot to tell I am using tween/tween.js.

Strange thing is, 

 

  this.mLogoMove = new TweenWrapper({x : this.mLogo.x , y : this.mLogo.y})    .to({y : 330} , 200)    .onUpdate((function(updatedVariables)      {        this.mLogo.y = 500 - updatedVariables.y;      }).bind(this))    .onComplete((function()      {        this.mStartButtonMove.start();      })    .bind(this))    .start();  this.mLogoMove.start();

 

the line this.mLogoMove.start() is undefined. Setting up breakpoints on instanciation still also undefine. That is crazy. Imagine I already instanciated an object and the var is still undefine, but you can still see the object fires up normally. Though I believe this is pure JS thing.
