AngularJS ng网格单选按钮问题

Question

我用单选按钮处理ng-grid。

单选按钮的cellTemplate如下：

cellTemplate: '<div class="user-radio"><input type="radio" name="rdUserList" ng-model="radioInitial" ng-change="selecteUserFromGrid(row.entity)"></div>'

根据无线电选择，我必须启用按钮

$scope.selecteUserFromGrid = function(rowEntity) {
    $scope.selectedUser = rowEntity;
    $scope.isUserSelectDisable = false;
};

我在这里面临两个问题：

1） 如果我选择任何单选按钮并更改排序顺序，则单选按钮的位置不会随所选行移动。例如：如果我为Ashwin[第一行]的行选择单选按钮并更改排序顺序，则第一行仍然选择单选按钮，而不是记录。

2） 用于在再次搜索时清除现有单选按钮，使用代码：$('input[name=rdUserList]').attr('checked', false);。但这导致了一个问题，即当我再次搜索并从网格中选择同一行时，select按钮未启用

var app = angular.module('myApp', ['ngGrid']);
app.controller('MyCtrl', function($scope, $filter) {
    //Initiate 
    $scope.showGrid = false;
    $scope.radioInitial = false;
    $scope.isUserSelectDisable = true;
    $scope.selectedUser = [];
    // Actual result
    $scope.myData = [{
        firstName: "Vedikka",
        lastName: "Vasu",
        empNumber: 24,
        changeable: false
