angularjs - 親テーブルの未加工アイテムのみを編集可能にする方法は?

Question

編集ボタン ( ng-click="editmode = !editmode") をクリックすると、テーブル全体がinput表示されます。<input type="text">編集可能としてのみ表示することを示す解決策はありますか?

var app = angular.module('myapp', []);
app.controller('testController', function($scope) {
  $scope.userdetails = {
    "id": "1",
    "user_id": "2",
    "name": "Alycia",
    "address": "510 Marks Parkway Suite 221\nLake Karelle, SC 01791",
    "post": "Howellmouth",
    "district": "Schaeferside",
    "state": "New Mexico",
    "pin": "61354-9529",
    "phone": "(239)009-2861x858",
    "mobile1": "+70(1)8058651903",
    "mobile2": "+69(3)0049980344",
    "file_id": "1",
    "email1": "Diana11@Sipes.info",
    "email2": "Dietrich.Georgianna@hotmail.com",
    "created_at": "2015-08-04 11:41:56",
    "updated_at": "2015-08-04 11:41:56"
  };
});
