title: Event for ckeditor content changed
body: <p>If possible, how can we to the event of ckeditor's content being changed? For instance, there's some text already inserted into the ckeditor's content aka textarea when the page is opened. Afterwards I type something more or delete some of that text. Is there some event that's fired I can get to to change a variable when the text is changed?</p>
  
  <p>I have this for regular textareas:</p>
  
  <pre><code>$("input,textarea").on("input", function () {
      booleanvar= true;
  });
  </code></pre>
  
  <p>Saw a possible solution somewhere that had this:</p>
  
  <pre><code>$('.ckeditor').ckeditorGet().on('key', function (e) {
      //some code
  });
  </code></pre>
  
  <p>Tried it, but didn't work. And yes I know my ckeditor's textarea has "ckeditor" as its class so that's not the reason for it not to work.</p>
  
  <p>So something like those examples I can use to get to some sort of textchanged event of ckeditor?</p>
