ADG is not picking up changes from this getter

Question

My ADG is not picking up changes from this getter, is it because the whole class needs to implement IEventDispatcher ?
<mx:AdvancedDataGridColumn headerText="Delete" dataField="reviewDate" visible="{userModel.loggedInUser.deleteReview}" id="deleteColumn">
UserModel.as
    [Bindable(event="propertyChange")]
        public function get loggedInUser():User
            return _LoggedInUser;
    public function set loggedInUser(value:User):void
            _LoggedInUser = value;
            //loggedInUserModified.dispatch();
            eventDispatcher.dispatchEvent (new Event ("propertyChange"));
