Why doesn't the menu button work?

Question

css

I understand that the problem is in connecting scripts. When I did it myself on my theme, everything worked, and after I switched the site to the Bootstrap Basic theme, it stopped.

if (!function_exists('bootstrapBasicEnqueueScripts')) {
    /**
     * Enqueue scripts & styles
     */
    function bootstrapBasicEnqueueScripts() 
    {
        global $wp_scripts;

        wp_enqueue_style('bootstrap-style', get_template_directory_uri() . '/css/bootstrap.min.css', array(), '3.3.7');
        wp_enqueue_style('bootstrap-theme-style', get_template_directory_uri() . '/css/bootstrap-theme.min.css', array(), '3.3.7');
        wp_enqueue_style('fontawesome-style', get_template_directory_uri() . '/css/font-awesome.min.css', array(), '4.6.3');
        wp_enqueue_style('main-style', get_template_directory_uri() . '/css/main.css');

        wp_enqueue_script('modernizr-script', get_template_directory_uri() . '/js/vendor/modernizr.min.js', array(), '3.3.1');
        wp_register_script('respond-script', get_template_directory_uri() . '/js/vendor/respond.min.js', array(), '1.4.2');
        $wp_scripts->add_data('respond-script', 'conditional', 'lt IE 9');
        wp_enqueue_script('respond-script');
        wp_register_script('html5-shiv-script', get_template_directory_uri() . '/js/vendor/html5shiv.min.js', array(), '3.7.3');
        $wp_scripts->add_data('html5-shiv-script', 'conditional', 'lte IE 9');
        wp_enqueue_script('html5-shiv-script');
        wp_enqueue_script('jquery');
        wp_enqueue_script('main-script', get_template_directory_uri() . '/js/main.js', array(), false, true);
        wp_enqueue_script('bootstrap-script', get_template_directory_uri() . '/js/vendor/bootstrap.min.js', array(), '3.3.7', true);
        
        wp_enqueue_style('bootstrap-basic-style', get_stylesheet_uri());
    }// bootstrapBasicEnqueueScripts
}
add_action('wp_enqueue_scripts', 'bootstrapBasicEnqueueScripts');

I write the code for the button in main.js

$(document).ready(function() {

  $(".toggle-mnu").click(function() {
  $(this).toggleClass("on");
  $(".top_menu").slideToggle();
  return false;
});


});
