jquery cookie issue - does not open modal window - jquery-cookie

Question

I have small issue with jquery-cookie plugin, as you can see in functions.php , first I register script, then enqueue jquery_cookie_script, but does not work properly... I want to archive when user open website today, and scroll.Top() > 50% of window height, modal window will be opened. When close modal window by click on the X button, will not be able to open it again after refresh the whole page, only for 7 days.
You can see my code below, I need some help how to fix that issue, because does not work at all.
jQuery(document).ready(function($) {
$(window).scroll(function(event) {
var y = $(this).scrollTop();
var half_height = $(window).height() / 2;
if (y > half_height) {
if ($.cookie('modal_shown') == null) {
$.cookie('modal_shown', 'yes', {
expires: 7,
path: '/'
});
$('#modal').reveal();
}
}
});
});
in functions.php
function enqueue_custom_js(){
wp_enqueue_script('custom', get_stylesheet_directory_uri() . '/js/custom.js',array(),time());
wp_register_script( 'jquery_cookie_script', 'http://cdnjs.cloudflare.com/ajax/libs/jquery-cookie/1.4.1/jquery.cookie.min.js',array(),time());
wp_enqueue_script( 'jquery_cookie_script');
}
add_action('wp_enqueue_scripts','enqueue_custom_js');

I found a solution that works properly
jQuery( document ).ready( function( $ ) {
$(document).on('scroll', function() {
var y = $(this).scrollTop();
var half_height = $(window).height()/2;
if (y > half_height) {
$(document).off('scroll');
if ($.cookie('pop') == null) {
$('#modal').modal('show');
$.cookie('pop', '7');
}
}
});
});
