Fancybox when loading ajax makes all loaded links and scripts display:none, how to fix it?

Question

JavaScript

I use this design https://codepen.io/fancyapps/pen/yxmrWZ?editors=1100
in loading the page with the following. content:

<style>....</style>
<link rel="stylesheet" href="...">
<link rel="stylesheet" href="...">
<link rel="stylesheet" href="...">
<div>
    <div>
        CONTENT
    </div>
</div>
<script src="..."></script>
<script>...</script>

so after clicking, the content field is loaded, but all links and scripts have the display none property, what am I doing wrong or how to deal with this please tell me
