AngularJS ~ Refresh pagination after Ajax request

Question

I 'm a beginner in AngularJS. I have created a page that retrieves records from database along with total records using an Ajax call. After populating the grid with the records, I wanted to refresh the pager control based on values received from the Ajax call such as the total records and the current page number as 1. I'm seeing the pager but is not refreshed. Can you please verify and let me know what I'm missing here?

var angularPersonModule = angular.module("angularPersonModule", ['ui.bootstrap']);
angularPersonModule.controller("AngularPersonController", AngularPersonController);
angularPersonModule.controller("PaginationController", PaginationController);
angularPersonModule.factory("PaginationService", PaginationService);

PaginationController.$inject = ['$scope', '$timeout', '$rootScope', 'PaginationService'];

function PaginationController($scope, $timeout, $rootScope, PaginationService) {
  $scope.setPage = function(pageNo) {
    if ($scope.currentPage === pageNo) {
      return;
    }

    $scope.currentPage = pageNo;
    $rootScope.$broadcast("personPageChanged", $scope.currentPage);
    alert("call from setPage");
  };

  $scope.pageChanged = function() {
    var i = 0;
  };

  $scope.$on('personRefreshPagerControls', function(event, args) {
    //the solution:
    setTimeout(function() {
      //setTimeout is a deffered call (after 1000 miliseconds) 
      $timeout(function() {
        $scope.totalItems = PaginationService.getTotalRecords();
        $scope.currentPage = PaginationService.getPageNumber();
        $scope.itemsPerPage = PaginationService.getPageSize();
        $scope.numPages = PaginationService.getPageCount();
        alert("totalItems = " + $scope.totalItems);
        alert("currentPage = " + $scope.currentPage);
        alert("itemsPerPage = " + $scope.itemsPerPage);
        alert("pageCount = " + $scope.numPages);
      });

    }, 900);

  });
}

AngularPersonController.$inject = ['$scope', '$rootScope', 'AngularPersonService', 'PaginationService'];

function AngularPersonController($scope, $rootScope, AngularPersonService, PaginationService) {
  $scope.getAll = function() {
    $scope.persons = AngularPersonService.search();
    PaginationService.setTotalRecords(3);
    PaginationService.setPageNumber(1);
    PaginationService.setPageSize(2);
    PaginationService.setPageCount(2);
    $rootScope.$broadcast("personRefreshPagerControls", 3);
  }

  $scope.$on('personPageChanged', function(event, args) {
    alert("pageChanged Event fired");
    alert("Received args = " + args);
    $scope.getAll();
  });

  $scope.getAll();
}

function PaginationService() {
  var currentPage = 1;
  var pageCount = 2;
  var pageSize = 2;
  var totalRecords = 3;

  return {
    getPageNumber: function() {
      return currentPage;
    },
    setPageNumber: function(pageNumber) {
      currentPage = pageNumber;
    },
    getPageSize: function() {
      return pageSize;
    },
    setPageSize: function(newPageSize) {
      pageSize = newPageSize;
    },
    getTotalRecords: function() {
      return totalRecords;
    },
    setTotalRecords: function(newTotalRecords) {
      totalRecords = newTotalRecords;
    },
    getPageCount: function() {
      return pageCount;
    },
    setPageCount: function(newPageCount) {
      pageCount = newPageCount;
    }
  }
}

angularPersonModule.factory("AngularPersonService", function($http) {
  return {
    search: function() {
      return [{
        "Name": "Hemant"
      }, {
        "Name": "Ashok"
      }, {
        "Name": "Murugan"
      }];
    }
  }
});

Update

Now I have updated the snippet so that you can execute and see the result manually.
