title: JQuery bind on Ajax success
body: <p>Why do we call bind on <strong>AJAX</strong> <code>success</code> calls?</p>
  <p>Take a look at this code:</p>
  <pre class="lang-js prettyprint-override"><code>$.ajax({
      url: myurl,
      dataType: 'json',
      success: function(data){
          this.setState({data: data});
      }.bind(this)
  });
  </code></pre>
  <p>If we don't call <code>bind</code>, then does it makes any difference or there is an advantage to use <code>bind</code> here?</p>
