- There is a cascade semicolon missing after #serializeForm, but it
probably doesn't matter much.

- You likely want to return false to the click handler, otherwise a
full submit will be triggered. You can do this by adding

      (html jQuery ajax
          serializeForm;
          onSuccess: ...;
          return: false)

> If I execute this by clicking the button the callback for the textArea

If the AJAX call is faster you get the AJAX submit, then a full submit.

If the full submit is faster, the AJAX call is cancelled by the
browser and you get only one submit.
