Here is one using dojox.mvc.Repeat as a mixin with no Group and dojo.parser instead of dojox.mobile.parser it is all good using mixin.
(dojox/mobile/ListItem has a limitation, assuming that the enclosing widget is the parent list widget. We cannot use dojox/mvc/Templated for list items therefore. Also, there seems a bug in _setCheckedAttr(), not actually setting "checked" attribute unless _isOnLine is true)
You can update the label or checked from here to update the model.
