Doing like this
model.push(qx.data.marshal.Json.createModel({label: "Another new item"}))
and one another item to be added =)
Items in qx.data.Array() are qooxdoo objects. The createModel constructs
class and creates an instance (every property get/set accessors and event).
So, model.getItem(N) will return qooxdoo object with label property.
