I am unable to bind a function to my Kendo viewmodel. It does not give an error message and simply does not bind even though other viewmodels on my page are working.


var Ccf;
(function (Ccf) {
    var ViewModels;
    (function (ViewModels) {
        var User;
        (function (User) {
            var defaultAddModel = {
                labelIds: []
            };
            var InfoViewModel = (function (_super) {
                __extends(InfoViewModel, _super);
                // parentViewModel must begin with an underscore, otherwise kendo will wrap it in an observable object.
                function InfoViewModel(_parentViewModel) {
                    _super.call(this);
                    this._parentViewModel = _parentViewModel;
                    this.data = new kendo.data.ObservableObject();
                    this.messages = new kendo.data.ObservableArray([]);
                    _super.prototype.init.call(this, this);
                }
                InfoViewModel.prototype.add = function (e) {
                    e.preventDefault();
                    if (!this._parentViewModel.addViewModel) {
                        // Initialize and bind the view model for the modal window.
                        this._parentViewModel.addViewModel = new AddViewModel(this._parentViewModel, defaultAddModel);
                        kendo.bind(this._parentViewModel.addModal, this._parentViewModel.addViewModel);
                    }

The HTML that that binds to the viewmodel:

The page itself has several viewmodels being initialized and this is the only one that is having issues. The others are working fine with the same code structure and function calls. Here is where the viewmodels are being initialized: 

 


var Ccf;
(function (Ccf) {
    var ViewModels;
    (function (ViewModels) {
        var User;
        (function (User) {
            var UserProfileViewModel = (function () {
                function UserProfileViewModel(options) {
                    this.options = options;
                    this.infoViewModel = new User.UserProfileInfoViewModel(options);
                    this.childrenViewModel = new User.UserProfileChildrenViewModel(options);
                    this.diagnosisViewModel = new User.UserProfileDiagnosesViewModel(options);
                    this.labelViewModel = new User.UserProfileLabelsViewModel(options);
                    this.languageViewModel = new User.UserProfileLanguagesViewModel(options);
                    this.referralSourceViewModel = new User.UserProfileReferralSourceViewModel(options);
                    this.settingsViewModel = new User.UserSettingsViewModel(options);
                    this.notesViewModel = new User.UserProfileNotesViewModel(options);
                }
                UserProfileViewModel.prototype.initialize = function () {
                    this.infoViewModel.initialize();
                    this.childrenViewModel.initialize();
                    this.diagnosisViewModel.initialize();
                    this.labelViewModel.initialize();
                    this.languageViewModel.initialize();
                    this.referralSourceViewModel.initialize();
                    this.settingsViewModel.initialize();
                    this.notesViewModel.initialize();
                };
                return UserProfileViewModel;
            }());
            User.UserProfileViewModel = UserProfileViewModel;
        })(User = ViewModels.User || (ViewModels.User = {}));
    })(ViewModels = Ccf.ViewModels || (Ccf.ViewModels = {}));
})(Ccf || (Ccf = {}));

The user profile view model gets initialized directly on the view with the .Net razor passing the user Id value:


$(function () {
            var vm = new Ccf.ViewModels.User.UserProfileViewModel({ userId: "@ViewBag.UserId", isCoordinator: @isCoordinator.ToString().ToLower() });
            vm.initialize();
        });

Hi Eric,

Could you, please, prepare and send us a small isolated runnable sample demonstrating the issue in question? If that is feasible, you would prepare that sample in our Dojo runner. This way I will be able to review and troubleshoot the case locally and provide you with further assistance.

No answers yet. Maybe you can help?
