Retrive data from service in other template

I have a service

.factory('myService', function($http, $q) {

var deffered = $q.defer();
var data = [];  
var myService = {};

myService.async = function() {
$http.get('/*some json file from http adress*/')
.success(function (d) {
    data = d;
    deffered.resolve();
});
    return deffered.promise;
};
myService.data = function() { return data; };

return myService;
});

and controller (for user state mainly)

.controller('Ctrl', function( myService, $scope) {
    myService.async().then(function() {
        $scope.dataarray = myService.data();
    });
});

ui-router

  .state('profile', {
    url: '/user/:login',
    templateUrl: 'userprofile.html', 
    controller: 'Ctrl',      
  })

and in user.html(the parent state of profile) I used (after ng-repeat user in dataarray )

ui-sref="profile({ login: user.login})

to go to my template for specific user page called userprofile.html

The final question is how get in userprofile.html whole date from json file connected to the specified user.login that I send through ui-sref to display eg. his name, avatar etc. from one json data entry. I think I have to use a some sort of new controller to use in profile state.
