Provisioning TermSets/Terms to Terms Store from Apps

I was reading Deploying Managed Metadata Fields by Luis Manez, in the blog he mentions about creating TermSets and Terms with PowerShell. I couldn't get it working and instead created an APP to provision the TermSets and Terms.

Below are brief steps:

1. Create a "App for SharePoint 2013" Project (SharePoint-hosted)

2. Open AppMainifest.xml and set the Permissions

3. below is the js code

	var hostweburl;
	var appweburl;
	var scriptbase = hostweburl + "/_layouts/15/";
	function InitiateTaxonomy() {
	hostweburl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
	appweburl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));
	$.getScript(scriptbase + "SP.Taxonomy.js",
	function () {
	$.getScript(scriptbase + "SP.RequestExecutor.js", CreateTerms);
	}
	);
	}
	function getQueryStringParameter(paramToRetrieve) {
	var params =
	document.URL.split("?")[1].split("&");
	var strParams = "";
	for (var i = 0; i < params.length; i = i + 1) {
	var singleParam = params[i].split("=");
	if (singleParam[0] == paramToRetrieve)
	return singleParam[1];
	}
	}
	function StartRequest() {
	$.getScript(scriptbase + "SP.RequestExecutor.js", CreateTerms);
	}
	function CreateTerms() {
	var locationTerms = [];
	var obj;
	locationTerms.push(obj = { Name: "Perth", Locale: 1033, GUID: "6E0FDC96-7E59-4545-820F-CCB8BFD0AB32" });
	locationTerms.push(obj = { Name: "Melbourne", Locale: 1033, GUID: "BE1C37D3-D98D-4447-9310-FDA3156E7EDE" });
	locationTerms.push(obj = { Name: "Sydney", Locale: 1033, GUID: "DBFDBA00-B08A-4B47-9152-AE084CD80EA5" });
	var obj1;
	var businessUnitTerms = [];
	businessUnitTerms.push(obj1 = { Name: "HR", Locale: 1033, GUID: "278707D7-52F8-4B49-9163-F9A0FC6650AF" });
	businessUnitTerms.push(obj1 = { Name: "IT", Locale: 1033, GUID: "9185E703-2D41-4D7A-BE5E-26A6BEA56960" });
	var context;
	var factory;
	var appContextSite;
	var siteCollection;
	var i;
	context = new SP.ClientContext(appweburl);
	factory = new SP.ProxyWebRequestExecutorFactory(appweburl);
	context.set_webRequestExecutorFactory(factory);
	appContextSite = new SP.AppContextSite(context, hostweburl);
	siteCollection = context.get_site();
	//Current Taxonomy Session
	var taxSession = SP.Taxonomy.TaxonomySession.getTaxonomySession(context);
	//Term Store under which to create the group.
	var termStore = taxSession.getDefaultSiteCollectionTermStore();
	context.load(termStore);
	context.executeQueryAsync(function () {
	var id = termStore.get_id();
	//Get site collection group
	var defaultGroup = termStore.getSiteCollectionGroup(siteCollection);
	context.load(defaultGroup);
	context.executeQueryAsync(function () {
	//Create New Term Set
	var newTermSet = defaultGroup.createTermSet("Location", "74A786C1-8613-4ED8-9680-13493D94AD45", 1033);
	var newTermSet1 = defaultGroup.createTermSet("BusinessUnit", "683E8BDE-D2A5-4D7F-B15F-789217B95F21", 1033);
	for (i = 0 ; i < locationTerms.length; i++) {
	var newTerm = newTermSet.createTerm(locationTerms[i].Name, locationTerms[i].Locale, locationTerms[i].GUID);
	context.load(newTerm);
	}
	for (i = 0; i < businessUnitTerms.length; i++) {
	var newTerm = newTermSet1.createTerm(businessUnitTerms[i].Name, businessUnitTerms[i].Locale, businessUnitTerms[i].GUID);
	context.load(newTerm);
	}
	context.executeQueryAsync(function () {
	$('#message').text("Terms Created");
	}, function (sender, args) {
	$('#message').text(args.get_message());
	});
	}, function (sender, args) {
	$('#message').text(args.get_message());
	});
	}, function (sender, args) {
	$('#message').text(args.get_message());
	});
	}

call the InitiateTaxonomy from the onGetUserNameSuccess method.

4. Deploy the app and verify by navigating to the Term Store Management.

Note: I used the publishing site template, the Site Collection was already created.
