title: Increase value of counter by one upon class creation/append
body: <p>Creating a system that increases the 'fault' counter by a value of one upon every wrong answer submitted. I'm doing this by having my system listen out for the creation of a class called "incorrectResponse". However, it appears to just add to the counter as soon as the page finishes loading and doesn't add any more values after that.</p>
  
  <p>Here is the code I've tried that isn't working.</p>
  
  <pre><code>  //*-- Fault counter --*//
    if (document.querySelectorAll('incorrectResponse')) {
      $('#fault-counter').html(function(i, val) { return val*1+1 });
    };
  </code></pre>
  
  <p>Any reason as to why this is the case?</p>
