如何在Kendo Grid (AngularJs)中过滤对象数组？

<div ng-app="myApp" ng-controller="myCtrl">
  <kendo-grid k-options="gridOptions"></kendo-grid>
</div>

angular.module("myApp", [])
  .controller("myCtrl", function($scope) {
    $scope.gridOptions = {
      dataSource: {
        data: [
          { id: 1, name: "John", age: 25 },
          { id: 2, name: "Jane", age: 30 },
          { id: 3, name: "Bob", age: 35 }
        ],
        filter: {
          logic: "and",
          filters: []
        }
      },
      columns: [
        { field: "id", title: "ID" },
        { field: "name", title: "Name" },
        { field: "age", title: "Age" }
      ],
      filterable: true
    };
  });

$scope.gridOptions.dataSource.filter.filters.push({ field: "age", operator: "gt", value: 30 });

$scope.gridOptions.dataSource.filter.filters.push({ field: "age", operator: "gt", value: 30 });
$scope.gridOptions.dataSource.read();
