Google Analytics event tracking function. Uses HTML5 data-attributes. Any anchor with the data-event="ga" will fire a Google Analytics event. The event details should also be specified as data-attributes: data-category, data-action, data-label. Requires jQuery > 1.4

jquery.ga-event.js

eventTracking = function () {
	$t = $('[data-event="ga"]');
	$t.click(function () {
		var gaCat = $(this).data('category') ? $(this).data('category') : '',
		gaAct = $(this).data('action') ? $(this).data('action') : '',
		gaLab = $(this).data('label') ? $(this).data('label') : '';
		try {
			_gaq.push(['_trackEvent', gaCat, gaAct, gaLab]);
		} catch (e) {
            		console.log(e);
		}
        });
}

I think there is a small mistake, inside the click handler you should not use $t but $(this).

Thanks doro, that's updated.
