AngularJs两个服务相互覆盖

Question

我们有两个angularjs服务。首先调用第一个服务以检索数据，然后调用第二个服务。在第二个服务的“自我”上添加断点时，它总是由第一个服务的“自我”填充。即包含“ isloadinggrid等”。是否有一个原因？我以为每个对象中的self对于服务对象都是唯一的。

(function () {
    'use strict';
angular.module('IPortal.Angular.Components.List.Shared.List.Factory', [])
        .service('listfactory', ['$http', 'loggingService', 'listApiLink', 'listFormRenderService', 'listGridRenderService', function ($http, loggingService, listApiLink, listFormRenderService, listGridRenderService) {
            self.Model = {
            IsLoadingGrid: false,
            IsLoadingForm: false,
            TotalColumns: 0,
            TotalRows: 0,
            List:[],
            ListGrid: [],
            ListForm: [],
            ListFormTemplateURL: '',
            ListGridTemplateURL: '',
            BaseDate: new Date(),
            PendingUpdates : [],
        };




        return {
            GetListbyId: function (id, listType) {
                self.GetListbyId(id, listType);
                return self.Model;
            },
            GetListDetailbyId: function (id, listType) {
                self.GetListDetailbyId(id, listType);
                return self.Model;
            },
            SaveAnswer: function (pendingQuestion) {
                var pendingAdd = true;

                if (self.Model.PendingUpdates.length > 0) {
                    self.Model.PendingUpdates = self.Model.PendingUpdates.filter(function (pendingValue) {
                        if (pendingValue.id === pendingQuestion.id) {
                                pendingAdd = true
                                return false
                        }
                        return true;
                    });
                }

                if (pendingAdd) {
                    self.Model.PendingUpdates.push(pendingQuestion)
                }
            },
            Save: function () {
                var y = self.Model.PendingUpdates;
            }
        };
        }]);
})();

            self.Model = {

            self.UpdataStatus = function (primaryKey, patientId, status, reason, accountId) {

            };

            self.RenderForm = function () {
                self.Model.ListFormTemplateURL = listFormRenderService.Render(self.Model.ListForm);
                self.Model.FormTemplateIsRendered = true;
            }


            return {
                UpdateStatus: function (primaryKey, patientId, status, reason, accountId) {
                    self.UpdataStatus(primaryKey, patientId, status, reason, accountId);
                    return self.Model;
                },
                Data: self.Model,
            };
        }]);

})();
