title: reload visual composer grid after ajax call
body: <p>I am currently implementing barba.js in a wordpress theme. I have managed to make most of the javascript functions to work properly after page change except the VisualComposer grid.</p>
  
  <p>Reading <a href="https://stackoverflow.com/questions/41708153/initializing-visual-composer-upon-ajax-content-load">this</a> thread I have managed to make Visual composer basic functions work except the grid via <code>window.vc_js();</code></p>
  
  <p>If I add <code>window.resize();</code> I get a <code>window.resize is not a function</code> error.</p>
  
  <p>In quite a few pages I also get the same error with <code>window.vc_js()</code> - <code>window.vc_js is not a function</code></p>
  
  <p>How can I initalize the vc_grid?
  Why do I get these error when Visual composer is actually active?</p>
  
  <p>Any help appreciated</p>
