Why does this not work?

google-analytics-trackevent.js

// init:

var _gaq = _gaq || [];
_gaq.push(['_setAccount', 'UA-FOOBAR-X']);

(function() {
  var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true;
  ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';
  var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s);
})();

// invokes

_gat._getTrackerByName()._trackEvent('book','test-3')
true

_gaq.push(['_trackEvent', 'book', 'test-2']);
0

_gaq.push(function() {
  var pageTracker = _gat._getTrackerByName();
  console.log(pageTracker._trackEvent('book','test','test if this works'));
});
true

// => Nothing comes up to google analytics.
