Wordpress core jQuery conflict

[admin]

function my_customize_scripts(){
wp_register_script('my-customizer-js', get_template_directory_uri() .'/js/customizer.js', array('jquery'), 1.0, true);
wp_enqueue_script('my-customizer-js');
}add_action('customize_controls_enqueue_scripts', 'my_customize_scripts', 1);

jQuery file enqueue with hook

customize_controls_enqueue_scripts

works only when page starts to load, but when loaded it's just stop working. And worse, all the

.change()

functions' execution result desapears. It worked fine before, and three days earlier just stop working.
This file,

customizer.js

has to enqueue with this hook

customize_controls_enqueue_scripts

, it will not work in customizer other wise. Well, at least as I know, cause I tried all other hooks.

This is how jQuery code wrapped in

customizer.js

jQuery(document).ready(function($){
//code here
}

inside has

change()

functions for elements depends on input.

I tried to

wp_derejister_script('jquery');

to dequeue the wordpress core jQuery and then add hardcoded Google api just before

wp_head

in my

header.php

, like

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>

and it worked, but it's not an option. I want the Wordpress core jQuery run on my website.
I tried to undo all the changes that I've done to

customizer.js

when it stopped working. Also I tried to reduce this file, and took off all events, except one. It didn't help either.
But the

alert();

that I put inside function is working just fine BTW.

So please, any help is appreciated.

P.S. I checked other js files, as I can see they work fine. I also tried to enqueue customizer.js the general way

wp_enqueue_script()

guess what, you right - it didn't work.
This is my first time I am asking question here, this is my last hope.
