Angular Service To Set And Retrieve Object Between Controllers

Question

I been trying to set an service object from a http post response to a controller and getting it from another controller.
The tutorials I seen in SO or sites are focused more on getting it from HTML input to a controller and another controller getting the value.

I would want to avoid using rootscope and I'm new to angular-js.

First Controller(To Put Data1 & Data2 in an object)

.controller('GetItem',function($scope, $http, $filter, $ionicPopup, $stateParams, $cordovaSQLite, $cordovaDatePicker, dataFactory){
    ...
    console.log(resp.data);
    var data1= resp.data.data1;
    var data2= resp.data.data2;
 }

2nd Controller (To get the object and retrieve data1 and data2)

Some pointers would be deeply appreciated!

Update1: (Save Function Works but Get Function Returns EMPTY):

.service('StoreService',function(){

 var data1=[]; //{} returns me an empty object

 this.save=function(data1){
 alert('DATA: '+ data1); //able to retrieve string
 this.data1=data1;

 };

 this.getData1=function(){
 alert('DATA1: '+ data1); //unable to get string
 return data1;

 };
})

This is the 2nd Controller which retrieve from service:

 .controller('unlock', function($scope, $timeout, dataFactory, $stateParams,StoreService) {

  function test(){
    console.log(StoreService.getData1());

Answer 1

@atinder answer is way to go. Here is the example of the service:

app.service('StoreService',function(){

  var data1={};
  var data2={};
  this.save=function(data1,data2){        
       this.data1=data1;
       this.data2=data2;

  };

  this.getData1=function(){

    return data1;

  };

  this.getData2=function(){

    return data2;

  };
});

Then in first controller:

.controller('firstController',function(StoreService){
    .....
    StoreService.save(resp.data.data1,resp.data.data2);
 });

In second controller:

.controller('secondController',function(StoreService,$scope){
    $scope.data1 = StoreService.getData1();
    $scope.data2 = StoreService.getData2();
 });

Answer 2

create a basic service with setters and getters. Inject the service into both the controllers. use setter in one controller and getter in the another.
