Visual Composer + JS = not executing the code

Question

Ive got a weird issue. I'm trying to apply to my wordpress page a piece of code which works perfectly inside codepen. You can find it here:

https://codepen.io/anon/pen/rzmWVE

JS Code:

jQuery(document).ready(function( $ ) {

        var vid = document.getElementById("bgvid");
        var pauseButton = document.querySelector("#btnplay");

        if(pauseButton) pauseButton.addEventListener("click", function() {
          if (vid.paused) {
            vid.play();
            $(".hide-section").fadeOut();
          } else {
            vid.pause();
            $(".hide-section").fadeIn();
          }
        });

        $('#videoreplay').click(function () {
        var vid = document.getElementById("bgvid");
        vid.currentTime = 0;
        });

    $(".notice1, .notice2, .notice3, .notice4, .notice5, .notice6, .notice7").hide();

       $("#cairns").hover(function(){ 
       $(".notice1").show();
     },function(){
       $(".notice1").hide();
   });

       $("#brisbane").hover(function(){ 
       $(".notice2").show();
     },function(){
       $(".notice2").hide();
   });

       $("#perth").hover(function(){ 
       $(".notice3").show();
     },function(){
       $(".notice3").hide();
   });

       $("#goldcoast").hover(function(){ 
       $(".notice4").show();
     },function(){
       $(".notice4").hide();
   });

       $("#sydney").hover(function(){ 
       $(".notice5").show();
     },function(){
       $(".notice5").hide();
   });

       $("#melbourne").hover(function(){ 
       $(".notice6").show();
     },function(){
       $(".notice6").hide();
   });

       $("#adelaide").hover(function(){ 
       $(".notice7").show();
     },function(){
       $(".notice7").hide();
   });
});

What I am doing wrong that this code is not working on a real website? I am reffering to the part from:

$(".notice1, .notice2, .notice3, .notice4, .notice5, .notice6, .notice7").hide();

till the end of code.

Composer simply ignores that.. I have no idea why. Can you help me with this issue? thanks..
