Here you a new reference to the form's model.
One way to solve the issue is to use a wrapped/delegating model:
new IModel<MasterBean>() {
public MasterBean getObject() { return form.getModel().getObject();}
public void setObject(MasterBean mb) { return
form.getModel().setObject(mb);}
public void detach() { return form.getModel().detach();}
}

Another way to solve it is to do: childPanel.setModel(rowModel);
