AngularJS Question

Update ng-model or $scope variables from controller

I am having some difficulties in updating textbox using Angularjs with ASP.Net MVC. I have

tag displaying
... When I click on Edit button, a textbox appears so I can edit the name that was displayed in the

I am using different ng-models in the
and the
because I don't want direct binding...

So, I am actually having two questions:

1- If I will use the same
in both sides, what if I wanted to cancel editing after entering text already?? The text will be changed anyway, is there a way to undo the change??

2- If not, then my second question, I need your help in updating the textbox
to get the value of the
when I click on Edit.

Below is my code:

My view:

<div ng-show="!nameElements" class="item_list">{{u.fName}}</div>
<div ng-show="nameElements">
<input type="text" id="ufn" ng-model="userfName">
<a href="javascript:void(0)" ng-click="updateUserName()"><i class="fa fa-floppy-o fa-lg" aria-hidden="true"></i></a>

My angular controller:

.then(function (response) {
$scope.users = response.data;
$scope.itmNo = response.length;
$scope.userfName = response[0].fName;//This is not working!!
.catch(function (e) {
console.log("error", e);
throw e;
.finally(function () {
console.log("This finally block");

So, the issue is, I am not able to change/update the ng-model from my controller.

I hope my question is clear

It seems to me likely that you were previously using .success(function (response) {...}) and changed it to .then(function(response) {...}.

The parameters for .success() and .then() callbacks are not the same. The first parameter passed to the .success() calback is the response.data value passed to .then().

Your code should probably be:

    .then(function (response) {
        var data = response.data
        $scope.users = data.data;
        $scope.itmNo = data.length;
        $scope.userfName = data[0].fName;
