KnockoutJS push object onto array inside an object

Question

Can someone tell me why this is not working?

function Event() {
    self.EventName = ko.observable();
    self.EventTypeID = ko.observable();
    self.EventTypeName = ko.observable();
    self.DepartmentID = ko.observable();
    self.DepartmentName = ko.observable();
    self.EventDescription = ko.observable();
    self.EventDate = ko.observable();
    self.EventItems = ko.observableArray([]);
    self.MembersAttended = ko.observableArray();
};

self.EventToAdd = new Event();
self.EventToAdd.EventName = 'test';
self.EventToAdd.EventItems.push(new EventItem(4));

I am getting that push is undefined.

Thanks!

Add var self = this; as the first line in your Event method. Without it, you are accidentally adding all of the properties to your container object instead of to your Event object.
