Dynamic WordPress editor in meta box

The problem is that the wp_editor() automatic load the scripts and this is not possible dynamic. You must enhance your plugin, code and add the scripts also dynamic or via ajax. WP include the scripts and styles via wp_enqueue_script() and this is not usable in a dynamic change of DOM, it was registered for better control.

Hints for find all script and styles.

The funciton wp_editor() is only a wrapper for the class class _WP_Editors and in this class do you find all method and inlcuded scripts. see in wp-includes/clas-wp-editor.php.
See the methods editor_settings and enqueue_scripts for include js and styles.
