Barebones google analytics RequireJS module wrapper for “universal analytics” with example of how to use it within a single page application

google-analytics.js

/**
 * Google analytics include (using "Universal Analytics")
 * https://gist.github.com/acusti/8718758
 */

/*global define */

define(function(require) {
	'use strict';
 
	var ga_amd;
	
	// Setup temporary Google Analytics objects
	window.GoogleAnalyticsObject = 'ga';
	window.ga = function() {
		(window.ga.q = window.ga.q || []).push(arguments);
	};
	window.ga.l = 1 * new Date();
	
	// Create a function that wraps `window.ga`
	// This allows dependant modules to use `window.ga` via amd module
	ga_amd = function () {
		window.ga.apply(this, arguments);
	};
	
	// Asynchronously load google's analytics.js; it will take over `window.ga` object after it loads
	// This allows us to add events to `window.ga` before the library has fully loaded
	require(['//google-analytics.com/analytics.js']);
	
	return ga_amd;
});

tracking.js

/**
 * Google analytics tracking
 */

/*global define */

define(function(require) {
	'use strict';
	
	var // Helpers
		ga              = require('app/google-analytics'),
		// Google analytics settings
		tracking_id     = '{{TrackingID}}',
		tracking_domain = '{{Domain}}';
	
	return {
		update : function() {
			var url = window.location.pathname;

			// Set up your pageview URL
			// To push the hash as a path, for example:
			url += window.location.hash.substr(1);

			// Track it
			ga('send', 'pageview', url);
		},
		init : function() {
			// Initialize analytics
			ga('create', tracking_id, tracking_domain);
			ga('send', 'pageview');
		}
	};
});

require(['//google-analytics.com/analytics.js']);

Does this code work with the current version of Google Analytics? I have been testing the code and ga shows me the amount of users online but it does not show me what screen is being viewed even when I call the update function. Please help
