How can i use `setSearchCompleteCallback(object,method)` from this [doc](https://developers.google.com/custom-search/docs/js/cselement-reference) with my code?

```
<script>
  (function() {
    var cx = '011685828559868923844:yxkryvmtqxm';
    var gcse = document.createElement('script');
    gcse.type = 'text/javascript';
    gcse.async = true;
    gcse.src = (document.location.protocol == 'https:' ? 'https:' : 'http:') +
        '//www.google.com/cse/cse.js?cx=' + cx;
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(gcse, s);

  })();
</script>

<gcse:search></gcse:search>

```
