JavaScript file doesn't load after page transition

Everything is working fine on my index.html. On the first .onload page all the images are draggable and all over the page

HERE THE PROBLEM:

However, when I WENT TO THE PAGE ABOUT.html AND GO BACK TO THE INDEX.html my script look like isn't working anymore and I can see only one image that is not even draggable anymore.

Have a closer look to my project here: https://codepen.io/cat999/project/editor/AEeEdg

HOW DO I FIX ISSUE? COULD SOMEBODY HELP ME TO FIX MY CODE?

var winWidth = window.innerWidth,
    winHeight = window.innerHeight,
    threeWinHeight = winHeight*3;

$(window).on('resize', function(){
  winHeight = window.innerHeight,
  twiceWinHeight = winHeight*2;
});

$('.shape').each(function(){
  var topPos = Math.floor(Math.random()*1300),

      //BE CAREFUL 7000px is less then total body height or  CAUSING OVERFLOW
      leftPos = Math.floor(Math.random() * winWidth);
  $(this).css('top', topPos + 'px');
  $(this).css('left', leftPos + 'px');
});

Draggable.create('.shape', {
  //type:"rotation",
  bounds: '.section-2',
  edgeResistance:0.65,
  throwProps:true,
});

var number = Math.floor((Math.random() *15) + 2);
var number2 = Math.floor((Math.random() * 0) + -15);
var number3 = Math.floor((Math.random() * 0) + 15);
var number4 = Math.floor((Math.random() * 0) + 6);
$(".shape--circle").css("transform", "rotate(" + number2 + "deg)");
$(".shape--square").css("transform", "rotate(" + number3 + "deg)");
$(".shape--circle-2").css("transform", "rotate(" + number4 + "deg)");

Additionally, the index and the about section has using barba.js. Here the list of my script:
