Mailchimp custom signup-form dont save anything

Ive made a JSFiddle with the signup-page which is also hosted here: https://copenhagenrecords.us1.list-manage.com/subscribe?u=0db7130efa25ec55bd8f6df27&id=c591a7ccd2

I've added all merge-tags and the various ID's but somehow the form still don't add anyone. Whats lacking?
