javascript/jquery-谷歌自定义搜索api-函数触发两次

我正在使用google搜索API中的代码以及我自己的jquery函数对控制台进行简单的日志记录，我注意到jquery函数被触发了两次。此外，还会抛出javascript错误（甚至在Google的示例页面上也会发生这种情况）

这是我的密码：

<script type="text/javascript">
        google.load('search', '1', {language : 'en'});
        google.setOnLoadCallback(function() {
            var customSearchControl = new google.search.CustomSearchControl('000638822871137547098:_xxgiq7wt_k');
            var linkTarget = "frame";
            //customSearchControl.setResultSetSize(google.search.Search.FILTERED_CSE_RESULTSET);
            //customSearchControl.draw('cse');

            // Use "mysite_" as a unique ID to override the default rendering.
            google.search.Csedr.addOverride("mysite_");
            customSearchControl.setLinkTarget(linkTarget)
            // Draw the Custom Search Control in the div named "CSE"
            customSearchControl.draw('cse');

            $('.gsc-search-button').click(function(){
                console.log('click');
            })

            // Execute an initial search
            //customSearchControl.execute("ajax");


        }, true);
    </script>

最后，这里是来自google代码的示例：

如何解决这些错误并修复双击问题？

看起来我做得不对-要做我想做的事情，最好使用JSON自定义搜索API-这里提供了文档：
