TinyMCE editor loaded through AJAX not working

Question

I've built a form that calls for an editor to be loaded through AJAX, but when I insert the fetched contents I get only a <textarea>. If I hit the toggle editor button, then the editor gets built, but it uses the default configuration for TinyMCE instead of how Joomla tries to configure it.

My Javascript:

$.ajax({
    method:'GET',
    url:'fetchEditor.php'
}).done(function(response) {
    $('#main').append(response);
});

fetchEditor.php:

<?php
$editor = JFactory::getEditor('tinymce');
echo $editor->display('text', '', 'auto', 'auto', 55, 15, false);
?>

I tried throwing in some Javascript to re-init TinyMCE for this editor, but it also just uses the default configuration instead of what Joomla uses.

Answer 1

After spending more time searching for possibilities, I found that Joomla includes the file /media/editors/tinymce/js/tinymce.min.js, and upon opening the uncompressed version of the file and reading through it, I saw that it has the function Joomla.JoomlaTinyMCE.setupEditors(); which handles the initialization of all instances of TinyMCE on the page.

So, after the AJAX loads the new editor, recalling Joomla.JoomlaTinyMCE.setupEditors(); will handle everything.
