title: jQuery this inside event
body: <p>I tought that I really understand use of <code>this</code> in jQuery/JS, but this showes me that I'm wrong. I wanted to add class on DOM element and I used this:</p>
  
  <pre><code>$("#content").on("click",function(){
      this.addClass("bonus");
  });
  </code></pre>
  
  <p>But nothing happened, so I changed second line of code to and it worked:</p>
  
  <pre><code> $("#content").addClass("bonus");
  </code></pre>
  
  <p>Shouldn't <code>this</code> in first example refer to <code>$("#content")</code> already?</p>
