Select multiple checkboxes using angularjs but unable to get selected one

I am trying to get the list of selected checkboxes using angularjs. But unable to get selected.

HTML code Here

                <input type="checkbox" id="product_"  class="form-control" ng-model="x.Selected"> 

            </div>
            <div class="item-name">
                
            </div>
        </div>

script code:

.controller('categorieCtrl', function($scope, $http) {

   $scope.result = [{
            id: 1,
            category_name: 'Apple',
            Selected: false
        }, {
            id: 2,
            category_name: 'Mango',
            Selected: false
        }, {
            id: 3,
            category_name: 'Orange',
            Selected: false
        }];



 $scope.myFunc = function () {
    debugger;


     var message = "";
            for (var i = 0; i < 3; i++) {
                if ($scope.result[i].Selected) {
                    var id = $scope.result[i].id;
                    var categoryName =  $scope.result[i].category_name;
                    message += "Value: " + id + " Text: " + categoryName + "\n";
                }
            }
    alert(message);
    };

});

In the above code i am not getting selected items. Please let me know how can i get selected items using angularjs.
