Angular + Websockets +数据渲染

我有Websockets使用的应用程序。在服务器上更改一些数据后，我从websocket得到一些消息，改变了什么，需要更新表中的数据。我从websocket获取数据，发送get请求获取数据，并用数据更新我的作用域，但我没有看到表中的变化。在美元范围。ordersList i保存从服务器获取的日期。

My websockets service:

var services = angular.module('services', []);
services.factory('EventService', ['$cookies',
    function($cookies) {
        var service = {};
        service.connect = function() {
            if (service.ws) {
                return;
            }
            var ws = new WebSocket("ws://" + window.location.host + "/events/");
            ws.onopen = function() {
                ws.send(JSON.stringify({
                    type: "auth",
                    token: $cookies.token
                }));
                console.log("Succeeded to open a conection");
            };
            ws.onerror = function() {
                console.log("Failed to open a connection");
            };
            ws.onmessage = function(message) {
                var obj = JSON.parse(message.data);
                if (obj.result) return;
                if (obj.id) {
                    setTimeout(function() {
                        service.callback(obj);
                    }, 1000)
                }
            };
            service.ws = ws;
        };
        service.subscribe = function(callback) {
            service.callback = callback;
        };
        return service;
    }
]);

如何在我的控制器中使用它:

EventService.subscribe(function(msg) {
            console.log('msg', msg);
            var item = $.grep($scope.ordersList, function(item) {
                return item.id == msg.id
            })
            if (item.length > 0) {
                item[0].status = msg.status
            } else {
                $scope.ordersList.push(msg);
            }
            $scope.$apply();
        });
        $scope.getOrders();
        EventService.connect();

和我的模板:

<tr item="parameter" ng-repeat="item in ordersList">
<td>{{item.id}}</td>
<td>{{item.symbol}}</td>
</tr>
