title: How to update tags under existing vocabulary in ckan?
body: <p>I recently added some tags to my existing vocabulary , but even after restarting my ckan application the new tags were not getting reflected in my UI(vocabulary is a select box and the tags are the different options under it , recently added two more options).
  I was able to get the new tags only when I deleted the vocabulary and tags from the backend and restarted the application</p>
  
  <p>is there any way to update my tag list , without a backend hack?</p>
