angularjs – ng-repeat在更改数组时不更新

我有一个ng-repeat,它在更改正在使用的数组中时没有更新.我已经研究了很长一段时间但似乎没有任何工作.最初,当页面加载时,ng-repeat显示数据集的第一页,在获取新数据(下一页)并使用此数据设置该数组时,ng-repeat没有注意到更改并且从不填充更新的数组.如果有人能引导我朝着正确的方向前进,我将不胜感激.

gatekeeper.controller('businessController',['$scope','siteService',function($scope,siteService) {

$scope.page = 1;
$scope.resultsPerPage = 50;
$scope.maxPaginationSite = 10;
$scope.pageCount = 0;
$scope.resultCount = 0;
$scope.getBusinessSites = [];

function getBusinessSites()
{
    siteService.getBusinessSites($scope.page,$scope.resultsPerPage).then(function(response) {
        $scope.getBusinessSites = response.data;
        console.log($scope.getBusinessSites);
        $scope.resultCount = response.data[0].QueryCount;
        $scope.page = response.data[0].Page;
        $scope.pageCount = Math.ceil($scope.resultCount / 50);
    });
}
getBusinessSites();
$scope.pageChanged = function () {
    $scope.page = this.page;
    getBusinessSites($scope.page,$scope.resultsPerPage);

};

}]);
