如何在 AngularJS 在ajax回调里通过设置ng-s

//js controller代码
var teamModule = angular.module("TeamModule", []);
teamModule.controller('GroupCtrl', function($scope, $http, $state, $stateParams) {
$scope.showLoading = false;
$scope.groupInfo = {};
$scope.toggleLoading = function(isShow){
$scope.showLoading = isShow;
};
$scope.saveGroup = function(){
$scope.toggleLoading(true);
//请求使用jquery进行发送
$.ajax({
url: 'group/save',
data: $scope.groupInfo,
dataType: 'json',
type: "post",
success: function(data){
console.log(data);
$scope.toggleLoading(false);
},
error: function(){
$scope.toggleLoading(false);
}
});
};
});
