How do you set $rootScope within Angular Service function? - angularjs

Question

I'm having trouble setting $rootScope for Angularjs.
Below is my function
App.controller('Controller',
function (UtilityService, $rootScope) {
var setSession = function () {
$rootScope.test = "yes"; // <-- I get this
UtilityService.getSession().success(
function () {
$rootScope.test = "No"; // <-- I don't get this How do I get/set this value?
});
};
setSession();
});
Additional Info:
One of the ways that might work is to set up a service that is interacted between multiple controllers. Does anybody know how to do this with the service returning an http.get json object.
I'm having trouble getting a dynamic scope in my controller that is instantiated within a service.

In order to address my issue I had to
1) Pass $rootScope into my 2nd controller
App.controller($rootScope) {
2) Set my 2nd controller's function to $rootScope
$rootScope.functionCall = function () {};
3) Set my passed value to $rootScope ($rootScope.orderId)
$rootScope.functionCall = function () {
Service.getItems($rootScope.orderId).success(
function(results) {
$scope.items = results;
});
};
4) within my utility controller, I loop through my results, parsing them, and setting them to $rootScope as you can see in #3 I am initializing "$rootScope.orderId"
angular.forEach(results, function (value, key) {
if (key != null) {
$parse(key).assign($rootScope, value);
}
});
5) I am re-calling the controller's function from within my service call! This is what did the magic for me putting my variable "in scope"
$rootScope.functionCall();
6) I am also testing to see if the function exist cause different pages utilize the utility code but may not have the function to execute
if (typeof $rootScope.functionCall == 'function')
var setSession = function () {
UtilityService.getSession().success(
function (results) {
// Place the rootscope sessions in scope
angular.forEach(results, function (value, key) {
if (key != null) {
$parse(key).assign($rootScope, value);
}
});
// Have to bypass "scope" issues and thus have to execute these fns()
if (typeof $rootScope.functionCall == 'function') {
$rootScope.functionCall();
}
});
};
setSession();

As I wrote before I would use $scope when possible and if you need to share data across multiple controllers you can use a service. The code should be something like:
var app = angular.module('myApp', []);
app.factory('$http', 'myService', function ($http, myService) {
var customers = {};
$http.get("http://www.w3schools.com/website/Customers_JSON.php")
.success(function (response) {
customers = response;
});
return {
customers: customers
};
});
app.controller('controller_one', function($scope, myService) {
$scope.serv = myService.customers;
});
app.controller('controller_two', function($scope, myService) {
$scope.serv = myService.customers;
});
