    var self = this;

    self.Status = Status;
    self.SaveAsDraft = ko.observable(false);
    self.SaveAsError = ko.observable(false);

    self.SaveAsDraft = ko.computed(function () {
        if (self.Status == window.itk.model.constant.Draft) {
            return window.itk.mytime.viewmodel.SaveAsDraft(true);       
        }
    }, self);

    self.SaveAsError = ko.computed(function () {
        if (self.Status == window.itk.model.constant.SaveError) {
            return window.itk.mytime.viewmodel.SaveAsError(true);
        }
    }, self);
