title: TweenMax scale bgImage
body: <p>Im trying to scale a background image up, and then down again, but cant get it to work, any ideas?
  It scales up the background fine, but it is like it never calls the "reverse" function ?</p>
  
  <pre><code>TweenMax.to(bg, 1, {
                  css: {
                      scaleX: 1.5,
                      scaleY: 1.5,
                      transformOrigin: "center center",
                      onComplete: reverse,
                      onCompleteParams: [bg]
                  },
                  delay: 0.2,
                  ease: Power3.easeInOut
              });
  
              function reverse(el) {
                  TweenMaxto(el, 0.6, {
                      css: {
                          scaleX: 1.0,
                          scaleY: 1.0,
                          transformOrigin: "center center",
                          autoAlpha: 1,
                      },
                      ease: Power2.easeOut
                  });
              }
  </code></pre>
