javascript - angularjs ng-gird 配置好数据后 页面不显示内容也不报错

1.我在配置项里 $scope.gridOptions={

                     $scope.gridOptions = {
                        columnDefs: columnDefs,
                        rowData: $scope.homepages,
                        enableSorting: true,
                        enableColResize: true,
                        rowSelection: 'single',
                          suppressLoadingOverlay: true,
                          rowSelected: rowSelected}

homepage是一个数组，我定义好了数据在里面，为什么页面上就不加载呢？

$scope.homepages=[];
                    if(data.code==0){
                        homepageTu(data);//初始化图表
                            $rootScope.mask=false;
                        angular.forEach(data.rows,function(value,key){
                            var homepage=[];
                            homepage.host_name=value.host_name;
                            homepage.img='';
                            homepage.traffic_period=value.traffic_period;
                            homepage.total_bytes=value.total_bytes;
                            homepage.total_bytes_precent=value.total_bytes_precent;
                            homepage.total_requests=value.total_requests;
                            this.push(homepage);
                        },$scope.homepages);
