Google Analytics（分析）事件跟踪-不起作用

我正在尝试使用Google Analytics（分析）跟踪来跟踪出站链接点击。到目前为止，尽管使用了此页面中的代码，但我仍然无法使Google Analytics（分析）注册任何东西。

这是我尝试跟踪链接的示例页面（在底部：“购买谁是甘地？”）：http : //ourhomeschoolforum.com/reviews/history-geography/who-was-ghandi/

这是页面上的代码：

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
  (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
  m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
  })(window,document,'script','//www.google-analytics.com/analytics.js','ga');

  ga('create', 'UA-{ID redacted}', 'auto');
  ga('send', 'pageview');

</script>

<script>
/**
* Function that tracks a click on an outbound link in Analytics
* This function takes a valid URL string as an argument, and uses that URL string
* as the event label. Setting the transport method to 'beacon' lets the hit be sent
* using 'navigator.sendBeacon' in browser that support it.
*/
var trackOutboundLink = function(url) {
   ga('send', 'event', 'outbound', 'click', url, {
     'transport': 'beacon',
     'hitCallback': function(){document.location = url;}
   });
}
</script>

这是我正在使用的href：

<h2 style="text-align: center;"><a href="http://www.rainbowresource.com/product/sku/059929" target="_blank" onclick="trackOutboundLink(‘Who was Ghandi?’); return false;">Buy <em>Who Was Ghandi?</em></a></h2>

我究竟做错了什么？“ Google Analytics（分析）实时”或“行为”>“事件”的“事件跟踪”部分未显示任何内容。我需要设定一个目标吗？
