Angularjs ng-model 没有从 json 填充

Question

我从 Angular 服务获取的 JSON 数据未填充 ng-model。我尝试将数据放入警报框中，例如alert(data.Usr_UserId)，但它在警报框中显示undefined。下面是我的代码。

1) 控制器

app.controller("myCtrl", function ($scope, myService, $mdDialog) {

GetAllEmployee();
//To Get All Records  
function GetAllEmployee() {
    var result = myService.getEmployees();
    result.then(function (data) {
        $scope.userlist = data.data;
    });
}
GetUserTypeList();
//To Get All Records  
function GetUserTypeList() {
    var result = myService.getUserType();
    result.then(function (data) {
        $scope.usertype = data.data;
    });
}
$scope.clickevent = function(user, item) {
    if (item.opType == 1) {
        edit();
        ListEmp(user);
    } else {
        deleteEmp(user);
    }
}    
function deleteEmp(user) {
    var getData = myService.DeleteEmp(user.Usr_Id);
    getData.then(function(msg) {
      alert('Employee Deleted');
        GetAllEmployee();
    }, function() {
        alert('Error in Deleting bbb');
    });
}  
function ListEmp(user) {
    var resultset = myService.getEmp(user.Usr_Id);
    resultset.then(function(data) {
        alert(data.Usr_UserFName);
        $scope.add_user.UserId = data.Usr_UserId;
        $scope.add_user.FirstName = data.Usr_UserFName;
        $scope.add_user.LastName = data.Usr_UserLName;
        $scope.add_user.phone = data.Usr_PhoneNum;
        $scope.add_user.UserType = data.Usr_Type;
        $scope.add_user.Password = data.Usr_Passowrd;
    });
}
$scope.AddUser = function (add_user) {
    var getData = myService.AddEmp(add_user.Usr_UserId, add_user.Usr_Passowrd, add_user.Usr_UserFName, add_user.Usr_UserLName, add_user.Usr_Type, add_user.Usr_PhoneNum);
    window.location.href = '/Home/UserList';
    GetAllEmployee();       
}})
.controller('WidthDemoCtrl', function ($mdDialog) {
var vm = this;

this.announceClick = function (index) {
    $mdDialog.show({
        controller: DialogCtrl,
        controllerAs: 'ctrl',
        templateUrl: '/Home/About',
        parent: angular.element(document.body),
        targetEvent: $event,
        clickOutsideToClose: true
    })
};})

2) 服务.js

app.service("myService", function($http) {
  //get All Users
  this.getEmployees = function() {
    return $http.get("/Home/GetAllUsers");
  };
  this.getEmp = function(employeeId) {
    var response = $http({
      method: "post",
      url: "/Home/GetUserById",
      data: JSON.stringify({
        Userid: employeeId
      })
    });
    return response;
  }
  this.DeleteEmp = function(employeeId) {
    var response = $http({
      method: "post",
      url: "/Home/DeleteUser",
      data: JSON.stringify({
        User: employeeId
      })
    });
    return response;
  }
  this.AddEmp = function(userid, password, fname, lname, type, phone) {
    var response = $http({
      method: "post",
      url: "/Home/AddNewUser",
      data: JSON.stringify({
        UserId: userid,
        UserPassword: password,
        UserFName: fname,
        UserLName: lname,
        UserType: type,
        UserPhoneNumber: phone
      })
    });
    return response;
  }
  this.getUserType = function() {
    return $http.get("/Home/GetUserType");
  };
})

3) CSHTML

   <md-content layout-padding>
      <div>
         <form name="userForm">
