Created a custom taxonomy, and it works. But the table that displays the taxonomies in the wp-admin does not update on adding and deleting a entry without reload but the “quick edit” works without reload.
I get the following when clicking Add taxonomy button;

Admin-ajax.php:

(This looks like an html file inside an xml file.)

P.S : Everything is working, but visible only after reload.
