title: Angular Bootstrap UI Popover does not appear
body: <p>I've bumped my head into this now for 30mins and cannot find what I'm doing wrong:
  I am including all needed modules (and others) in <em>index.html</em></p>
  
  <pre><code>&lt;script type="text/javascript" src="libs/angular1.5.8/angular.js"&gt;&lt;/script&gt;
  
  &lt;script type="text/javascript" src="libs/angular-route/angular-route.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/angular-file-upload.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/jquery/jquery.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/angular-scroll.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/angularGrid.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/angular-count-to.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="libs/angular-animate.js"&gt;&lt;/script&gt;
  &lt;script src="https://rawgit.com/srfrnk/re-tree/master/re-tree.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script src="https://rawgit.com/srfrnk/ng-device-detector/master/ng-device-detector.js" type="text/javascript"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/angular-ui-bootstrap/0.9.0/ui-bootstrap-tpls.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I tell it to use the bootstrap ui module in <em>app.js</em></p>
  
  <pre><code>var app = angular.module('app', ['ng', 'ngRoute','angularFileUpload', 'duScroll', 'angularGrid', 'countTo', 'ngAnimate', 'ui.bootstrap', 'ng.deviceDetector']);
  </code></pre>
  
  <p>and I am trying to add it inside an ng-repeat like this:</p>
  
  <pre><code>      &lt;button uib-popover="I appeared on mouse enter!" popover-trigger="mouseenter" type="button" class="btn btn-default"&gt;Mouseenter&lt;/button&gt;
  </code></pre>
  
  <p>what's wrong??</p>
