userControllers.controller('UserFormController', ['$scope', '$http', 
'$location', '$window', 'myFactory', function ($scope, $http, $location, 
$window, myFactory) {
var dataObj = "";
var config = { headers: { 'Content-Type': 'application/x-www-form urlencoded;charset=utf-8;' } }

$scope.submitForm = function (user) {
    myFactory.set(user);  // Set data to myFactory to share with ConfirmationController        
    dataObj = {
        "name": user.name,
