title: javascript - datatables reload button not visible
body: <p>EDIT: The button was not visible which was my original problem which is not yet solved. Thanks for the quick comments about the comma issue. </p>
  
  <p>I am a JS novice and new to datatables as well. I was taking the example posted here to define the button during initialisation: 
  <a href="https://datatables.net/extensions/buttons/custom" rel="nofollow noreferrer">https://datatables.net/extensions/buttons/custom</a></p>
  
  <p>But it seems to be not working (button is not visible). 
  JSFiddle link here: <a href="https://jsfiddle.net/gr5er1pj/222/" rel="nofollow noreferrer">https://jsfiddle.net/gr5er1pj/222/</a></p>
  
  <pre><code>$(document).ready(function (){
      var table =  $('#example').DataTable( {
      ajax: 'https://api.myjson.com/bins/qgcu',
      buttons: [
          {
              text: 'Reload',
              action: function ( e, dt, node, config ) {
                  dt.ajax.reload();
              }
          }
      ]
     } );
  });
  </code></pre>
