javascript - Google Event Tracker not firing -

i've got event tracker (located in main.js rather inline click handler) supposed fire when user clicks on item specific class. however, client reporting these event tracker never fire, or atleast never sees response them. however, other ga event trackers throughout site working. can see issues code below causing this?

the js function in main.js handles looks so:

$('.vote.complete').click(function() {     whence = "tocompleted";     vote_id = $(this).data('vote_id');     cid = $(this).data('campaign_id');      c_title = $('#outfitpair'+cid).data('campaign_title');     u_id = $('#outfitpair'+cid).data('other_id');      _gaq = window._gaq;      if(_gaq != undefined){       _gaq.push(['_trackevent', 'viewpreviousvote', c_title, u_id]);     }      $('#outfitpair'+cid).find('.button.vote').removeclass('to-vote');     $(this).addclass('to-vote');      $.get('/campaigns/new_pair?whence='+whence+'&vote_id='+vote_id)      return false; }); 

the html being clicked looks like:

<a href="#" class="button vote complete" data-vote_id="9490" data-campaign_id="5">    <span>01</span> </a> 

and script in layout header:

<script> var _gaq = _gaq || [];       _gaq.push(['_setaccount', 'ua-xxxxxxxx-x']);       _gaq.push(['_setdomainname', 'mywebsite.com']);       _gaq.push(['_trackpageview']);        (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);       })();        window._gaq = _gaq; </script> 

the ga debugger returns in js console upon loading web page, although nothing new shows when try trigger event tracker:

is other_id value assigned u_id number? jquery .data() try covert javascript value, , _trackevent can fail silently if opt_label parameter integer.

you can use .attr() fetch attribute value without conversion. try:

u_id = $('#outfitpair'+cid).attr('data-other_id');
