Hi, I can see this in tutorial "You can define onStart, onUpdate, onComplete, onReverse, and/or onReverseComplete event callbacks." But I cant find hou to use "onReverse()".  But "onReverseComplete()" is there. I want to call a function on every "onReverse() "  occures. (using slider or the reverse button). Edit: here the example how I want to use onReverse() See the Pen gLtoz by anon (@anon) on CodePen
