我认为我的Angular有一个逻辑问题，我需要一些帮助。 我们有一个连接到DB的服务，它获取保存的值，因此我们的Angular表单可以获取值并使用它们。这一切都已成立。
我的问题是，在我们的表单中，我们有1个单选按钮列表，使用ng-repeat生成列表和3个下拉列表。我们的下拉列表是触发和更新功能，以更新自己的值。我们根据单选按钮列表选择显示和隐藏下拉菜单（我将发布代码）。应该注意我们正在使用Umbraco CMS，这个控件正在使用，但这不是实际问题。
问题是，我们将我们的响应控制台单选按钮列表输出的值精确到我们选择的选项，但是当我选择其中一个下拉列表项时，下拉列表的值将返回到先前选择的值。任何帮助解决这个问题将不胜感激。
代码如下：
my.controller.js
angular.module("umbraco")
.controller("Our.GalaxyEventSelectorController", function ($scope, $routeParams, notificationsService, GalaxyEventSelectorResource) {
$scope.emptyList = [{}];
$scope.ETypeRadio = { 0: "NA", 1: "RepeatingTimedEvent", 2: "RepeatSingleDayEvent", 3: "SingleTimedEvent" };
GalaxyEventSelectorResource.getEventById($routeParams.id, $scope.model.alias).then(function (response) {
// console.log("REsponse: " + response);
console.log("intial load on DOM load")
var resp = (response.data.indexOf("{") > -1 ? angular.fromJson(JSON.parse(response.data)) : "");
