[Callback function with GSAP not working in Meteor]

Thank you, here is a brief codepen that shows the error i am getting as of now. 

See the Pen GZWdoq?editors=1011 by theller5567 (@theller5567) on CodePen

 

Console error: invalid onCompleteAll tween value: undefined

 

Basically i am trying to get each icon to animate in and as soon the animation is done per image i want to it to fadeout(opacity:0). Didn't think doing so would be too hard but i am losing hair over it.

 

I was finally able to get a callback to work but now when the first image is done animating it makes all the images fadeOut to opacity:0. So you basically only get to see about half of the images now cause their opacity is  set to 0 before they even animate in.

[Callback function with GSAP not working in Meteor]

I am unable to get the callback functionality to work while using Meteor framework. I have copied functions straight from the GSAP docs and i still get type error: this._callback is not a function. I have tried everything and looked everywhere for a solution but no dice. Please, any help would be greatly appreciated. If callbacks don't work with Meteor or i am just flat out doing something wrong please let me know.

 

I would add a codepen but i don't believe they have a Meteor framework to use.

 

Template.home.rendered = function(){

    TweenMax.staggerTo(".img", 1, {rotation:360, y:100, opacity: 1}, 0.5, myCompleteAll );

    function myCompleteAll() {

       console.log("all tweens complete");

      }

}
