title: EasyAutocomplete events - $(this) is always undefined
body: <p>I try to use <a href="http://easyautocomplete.com/" rel="nofollow">EasyAutocomplete</a> on several elements simultaneously
  but <code>$(this)</code> always undefined, why?</p>
  
  <pre><code>$("#city_selector_suggest, $city_two, #city_down").easyAutocomplete({
      url: "/templates/rm/js/ecity2.json",
  
      getValue: function(element) {
          return element.cdek_cityname;
      },
  
      list: {
          onChooseEvent: function() {
              var selectedItemValue = $(this).getSelectedItemData().cdek_id;
              console.log(selectedItemValue);
          },
          match: {
              enabled: true,
  
              method:  function(element, phrase) {
                  if(element.indexOf(phrase) === 0) {
                      return true;
                  } else {
                      return false;
                  }
              }
          }
      }
  });
  </code></pre>
