title: Jquery rotate not working
body: <p>I have a little button which i want to rotate when i click on it.
  I tried the most direct way, which in my opinion is: </p>
  
  <p><code>$(this).rotate(45);</code></p>
  
  <p>This is the way it looks in my code:</p>
  
  <pre><code>$(document).ready(function() {    
      $(function() {
          $('.fa-plus-circle').click(function() {    
              $(this).rotate(45);   
          });
      });
  });
  </code></pre>
  
  <p>I went to my browser and opened the console and this is what i saw there:</p>
  
  <p><img src="https://i.stack.imgur.com/8Anea.png" alt="console error"></p>
  
  <p>I tried changing the jquery library from the latest to 1.7.2, that didn't work either. I tried using something different after, I used </p>
  
  <p><code>$(this)slideUp</code>   </p>
  
  <p>And yup, that worked for some reason. It seems to have trouble with "rotate". </p>
  
  <p>Thanks in advance, </p>
