在angularjs中使用查询

Question

我的问题：在我从angularjs文件和Controller文件执行查询后，我无法显示我想要的数据。 这是我的Angularjs文件：

$scope.confirmCapnhat=function(p_id,dn_ngayLap){
            if($scope.p_id!="" && $scope.dn_ngayLap!="")
            {
                 var thang=dn_ngayLap.getMonth();
                var Nam=dn_ngayLap.getFullYear();
                if(thang>9)
                        var NamThang=Nam+"-"+thang; 
                else
                        var NamThang=Nam+"-0"+thang;

                $http.get(API+'diennuoc/'+p_id+'/'+NamThang+'/capnhat').then(successCallback,errorCallback);
                function successCallback(response){
                    // $scope.name = "John Doe";
                    console.log(response);
                    $scope.diennuoc=response.data;
                };
                function errorCallback(response){
                    $scope.sodauDien=0;
                    $scope.sodauNuoc=0;
                };  
            }
            else
            alert('Chưa chọn phòng hoặc ngày lập!');

        }

在我的路线文件（web.php）中，我定义为：Route::get('diennuoc/{p_id}/{dn_ngayLap}/capnhat','DienNuocController@capnhat'); 以下是我的Controller文件：

 public function capnhat($p_id,$dn_ngayLap)
    {

            $sql="select * from diennuoc where p_id='".$p_id."' and dn_ngayLap='".$dn_ngayLap."'";
            $diennuoc=DB::select($sql);
        return $diennuoc;
    }

当我在Blade.php源代码中运行它时，我点击源中间的一个按钮（ng-click =“confirmCapnhat（p_id，dn_ngayLap）”）。它不显示下面的数据。 我的Blade.php：

<div class="box box-default" ng-controller="DienNuocController">
        <div class="box-header with-border">
          <h3 class="box-title">Thêm điện nước</h3>
