So all component instances are created on the first render and then React stores them internally? What happens if you redefine a component function making it returning a different set of components, how Om/React knows the function must be run again so the new components are instantiated and replaces the old ones? You need to trigger a full render/reinstancing manually after redefinitions like that? How?
