Tracking events in Universal Analytics only partly working -

Tracking events in Universal Analytics only partly working -

currently using universal analytics on website that's tracking pdf downloads , i'm trying implement video well, see how many times video has been played.

<p><iframe width="482" height="271" src="video url" scrolling="no" frameborder="0" allowfullscreen="" onclick="ga('send', 'event', 'videos', 'play', 'eco-assistant', '10');"></iframe></p>

this actual page.

any thought why video plays not tracked?

many thanks, b.

another thing maintain in mind value attributed event should integer, not string. onclick code should following:

onclick="ga('send', 'event', 'videos', 'play', 'eco-assistant', 10);"

hope additional info helpful.
