title: How to set prevous-text and next-text attribute as HTML template in angular-ui bootstrap pagination directive
body: <p>I'm going to use <a href="http://angular-ui.github.io/bootstrap/#pagination">http://angular-ui.github.io/bootstrap/#pagination</a>
  I need to set 'previous', 'next' indicators as html.</p>
  
  <p>something like:</p>
  
  <pre><code>&lt;pagination 
      previous-text="'&lt;span class="glyphicon glyphicon-arrow-left"&gt;&lt;/span&gt;'"
      next-text="'&lt;span class="glyphicon glyphicon-arrow-right"&gt;&lt;/span&gt;'"
  &gt;
  &lt;/pagination&gt;
  </code></pre>
