title: Using same angular controller several places on the same page
body: <p>I would like to have a bootstrap navigation tab with unread message count.
  Also, on the Messages page I need to display current messages and delete them whenever asked.
  The problem is it appears the value in scope is not changed for the second div. I made a plunker with the demo - the issue is that second instance is not updated as expected. What am I missing? New to angular. Thank you.</p>
