title: Selectize.js - not showing options
body: <p>I have an array that I send from the backend, from which I create a new array of objects, for which I then use JSON.stringify to make it ready for the <code>selectize</code>, the array looks like this then:</p>
  
  <pre><code>[{"question":"Challenge question"},{"question":"Challenge question"},{"question":"Challenge question"}... and so on
  </code></pre>
  
  <p>I am trying to use that new array with selectize, but no option gets rendered:</p>
  
  <p>This is the script:</p>
  
  <pre><code>var engagementsOptions = [];
  icoop.engagements.map(function(item) {
     engagementsOptions.push({
          "question" : item
      });
  });
  
  $('#engagement_question').selectize({
      options: JSON.stringify(engagementsOptions),
      create: true,
  });
  </code></pre>
