title: Angular UI bootstrap datepicker pop-up not working when upgrading to version 0.11 from 0.10
body: <p>The angular-ui-bootstrap datepicker isn't popping up when clicked after upgrading to version 0.11. </p>
  
  <p>I've tried the <a href="https://github.com/angular-ui/bootstrap/pull/1922#issuecomment-40491716" rel="nofollow">recommended work around</a> which is setting </p>
  
  <pre><code>is-open="dt.open" ng-focus="dt.open=true"
  </code></pre>
  
  <p>this works when it is enabled on just one calendar but not if there are two on the same page (both open and they are unusable). Anyone know a better work around that does not pollute the scope?</p>
  
  <p>I've also tried changing ng-focus to ng-click and had no luck with that. </p>
