Cube port with bootstrap load module

I am using cubeportfolio.js as part of the bootstrap template. It seems to work, but the custom .js part of the template throws an error in the console.

The template used can be seen here , which works without errors.

Error: "Unused error: cubeportfolio has already been initialized. Destroy it before reinitializing!"

For privacy reasons, I can't post all the code, but I called jquery.cubeportfolio.min.js at the bottom of the table with custom .js at the bottom.

Here is a custom .js

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

var gridContainer = $('#grid-container'),
    filtersContainer = $('#filters-container'),
    wrap, filtersCallback;


/*********************************
    init cubeportfolio
 *********************************/
gridContainer.cubeportfolio({
    layoutMode: 'grid',
    rewindNav: true,
    scrollByPage: false,
    defaultFilter: '*',
    animationType: 'slideLeft',
    gapHorizontal: 0,
    gapVertical: 0,
    gridAdjustment: 'responsive',
    mediaQueries: [{
        width: 800,
        cols: 3
    }, {
        width: 500,
        cols: 2
    }, {
        width: 320,
        cols: 1
    }],
    caption: 'zoom',
    displayType: 'lazyLoading',
    displayTypeSpeed: 100
});


/*********************************

if (filtersContainer.hasClass('cbp-l-filters-dropdown')) {
    wrap = filtersContainer.find('.cbp-l-filters-dropdownWrap');

    wrap.on({
        'mouseover.cbp': function() {
            wrap.addClass('cbp-l-filters-dropdownWrap-open');
        },
        'mouseleave.cbp': function() {
            wrap.removeClass('cbp-l-filters-dropdownWrap-open');
        }
    });

    filtersCallback = function(me) {
        wrap.find('.cbp-filter-item').removeClass('cbp-filter-item-active');
        wrap.find('.cbp-l-filters-dropdownHeader').text(me.text());
        me.addClass('cbp-filter-item-active');
        wrap.trigger('mouseleave.cbp');
    };
} else {
    filtersCallback = function(me) {
        me.addClass('cbp-filter-item-active').siblings().removeClass('cbp-filter-item-active');
    };
}

filtersContainer.on('click.cbp', '.cbp-filter-item', function() {
    var me = $(this);

    if (me.hasClass('cbp-filter-item-active')) {
        return;
    }

    // get cubeportfolio data and check if is still animating (reposition) the items.
    if (!$.data(gridContainer[0], 'cubeportfolio').isAnimating) {
        filtersCallback.call(null, me);
    }

    // filter the items
    gridContainer.cubeportfolio('filter', me.data('filter'), function() {});
});


/*********************************

gridContainer.cubeportfolio('showCounter', filtersContainer.find('.cbp-filter-item'), function() {

    var match = /#cbpf=(.*?)([#|?&]|$)/gi.exec(location.href),
        item;
    if (match !== null) {
        item = filtersContainer.find('.cbp-filter-item').filter('[data-filter="' + match[1] + '"]');
        if (item.length) {

        }

})(jQuery, window, document);
