You need to place your Script after the other components render; the name is
assigned inside renderComponent() and persists afterwards.
This is the way it is because we don't know how many times a component will
render within the same form (i.e., the magic of Foreach).
BTW, welcome to the world of meta-programming ... where you program the
system how to program!
