Google Analytics Events for li items

I'm trying to add Google Analytics click tracking events to li list items (active thumbnails) used in a responsive grid application, and can't get it working. I've researched here and in the Google developer forums without success. I'm sure there is something simple I'm doing wrong. I have the latest GA script code installed (page view analytics are working fine). Here is a code sample:

<ul>
	<li data-type="link" data-url="http://www.dianagabaldon.com/books/outlander-series/" data-target="_self" >
    <a href="#" onClick="_gaq.push(['_trackEvent', 'GridLinks', 'Click', 'Outlander Clicks 1']);"></a></li>
	<li data-thumbnail-path="outlander_files/thumbnails/outlanderbookseries1.png" ></li>
	<li data-thumbnail-text >
		<p class="largeLabel" >Diana Gabaldon -  Outlander Series</p></li>
</ul>

Hope you can help. Feel free to suggest a better way of doing it.

Update: I'm still digging, and the GA code has been updated for Universal Analytics and looks like this:

<ul>
	<li data-type="link" data-url="http://www.dianagabaldon.com/books/outlander-series/" data-target="_self" >
       <a href="#" onClick="ga('send', 'event', 'thumbnail', 'click', 'Outlander Clicks 1');"></a></li>
	<li data-thumbnail-path="outlander_files/thumbnails/outlanderbookseries1.png" ></li>
	<li data-thumbnail-text >
		<p class="largeLabel" >Diana Gabaldon -  Outlander Series</p></li>
</ul>

Update 2: I tried opening the outbound link target in a new page to see if a lack of callBack might be the problem. No success. Following are two views of the code, one with the <a href=> contained inside the li with the outbound link, the other in a separate li with the same parent ul. Neither works. Does anyone know which syntax is correct? Thx.

Example 1: With href in it's own li:

<ul>
	<li><a href="#" onclick="ga('send', 'event', 'thumbnail', 'click', 'Outlander Clicks 1');"></a></li>
    <li data-type="link" data-url="http://www.dianagabaldon.com/books/outlander-series/" data-target="_blank" ></li>
	<li data-thumbnail-path="outlander_files/thumbnails/outlanderbookseries1.png" ></li>
	<li data-thumbnail-text >
		<p class="largeLabel" >Diana Gabaldon -  Outlander Series</p></li>
</ul>

Example 2: With href inside outbound link li:

<ul>
	<li data-type="link" data-url="http://www.starz.com/outlandercommunity/home.html" data-target="_blank" >
        <a href="#" onclick="ga('send', 'event', 'thumbnail', 'click', 'Outlander Clicks 2');"></a></li>
	<li data-thumbnail-path="outlander_files/thumbnails/community1.png" ></li>
	<li data-thumbnail-text >
		<p class="largeLabel" >Starz:  Outlander Community</p></li>
</ul>
