title: Using .not() with bootstrap popover
body: <p>I am using bootstrap popovers</p>
  
  <pre><code>$('[data-toggle=popover]').popover();
  </code></pre>
  
  <p>I need to modify this code to prevent launching popover if the element has certain data attribute.</p>
  
  <pre><code>$('[data-toggle=popover]').not('[data-nopopover=1]').popover();
  </code></pre>
  
  <p>For some reason the popover is still triggered, even though the data attribute is present. </p>
  
  <p>HTML</p>
  
  <pre><code>&lt;span data-container="body" data-toggle="popover" data-placement="right" data-html="true" data-content="popover content" aria-hidden="true" data-original-title="" title=""&gt;&lt;/span&gt;
  </code></pre>
  
  <p>What am I missing?</p>
