ng-show="my.message" is set to true in http success but it doesn't update the view.
Here is my code:
Controller Js:
  lgControllers.controller('FormCtrl', function($scope, $http) {
                $scope.my = {
                    message: false
                };
                $scope.submitForm = function() {                       
                    $http({
                        url: "../saket/ajax.php",
                        data: "email_id=" + $scope.form.emailaddress + "&category_id=" + cat_num + "&action=subscribe",
                        method: 'POST',
                        headers: {
                            'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
                        }
                    }).success(function(data) {
                            $scope.my = {
                                message: true
                            };
                        console.log(data); // http is success
                        console.log($scope.my.message); // gives true
                    }).error(function(err) {
                        "ERR", console.log(err)
                    })
                };
            });
Index.html:
    <div ng-controller="FormCtrl">
        <div ng-show="my.message">It worked!</div>
    </div>
my.message gives true in console but the div remains hidden in the view.
I can't figure out where the problem is.
                        
Can it be that you are overwriting the message property, and angularjs is loosing the reference?
try just :
