QML Dynamic Object Management docs are incorrect/incomplete

The example at
http://doc.qt.nokia.com/4.7-snapshot/qdeclarativedynamicobjects.html

"QDeclarativeComponent: Created graphical object was not placed in the graphics scene.

file:///C:/Documents and Settings/Jason/My Documents/QmlPlaza/main.qml:8: TypeError: Result of expression 'MyModule.createSpriteObjects' [undefined] is not a function."
