Accordion not working properly with dynamic content

[mhutch26]

a newbie here... I have an accordion that's content is being brought in through includes. The accordion is showing up but with all the tabs in the open position and they won't toggle open/close. I'm completely stuck on how to get these to work with the accordion content being brought in dynamically. This is the code that works on the normal content accordions:

(function($, window, document, undefined) {
'use strict';

$(document).ready(function() {

/\*\*
 \* Accordions ===========================
 \* Save DOM selectors.
 \*/
var $container\_class = $('.accordions');
var $default\_class = $('.beefup');
var $toggle\_buttons\_class = $('.toggle-buttons');

/\*\*
 \* default options.
 \*/
var $default\_options = {
    openSingle: true,
    openSpeed: 300,
    closeSpeed: 300
};

/\*\*
 \* default settings.
 \*/

// we have accordions selector?
if ($container\_class.length) {

    // loop throw main containers
    $container\_class.each(function() {

        // we have beefup selector?
        if ($default\_class.length) {
            $(this).find($default\_class).beefup($default\_options);
        }

    });

}

// we have toggle buttons selector?
if ($toggle\_buttons\_class.length) {

    $toggle\_buttons\_class.each(function() {

        var $this = $(this);
        var $beefup = $this.find($default\_class).beefup($default\_options);

        // open all
        $this.find('.toggle-open-all').on('click', function() {
            $beefup.open();
        });

        // close all
        $this.find('.toggle-close-all').on('click', function() {
            $beefup.close();
        });

        // open accordion using button
        $this.find('.buttons-group').find('.button').each(function(index) {
            $(this).on('click', function() {

                if (!$(this).hasClass('toggle-open-all') && !$(this).hasClass('toggle-close-all')) {

                    $this.find($container\_class).find($default\_class).each(function(item) {

                        if (index === item) {
                            $beefup.click($(this));
                        }

                    });

                }

            });
        });

    });

}

The classes are different for the dynamic accordion, I tried to change
