Does this package work with stateless components?

Hi, I'm getting the following errors when calling <NumberInput> within a stateless component.

const X = () => (
  <NumberInput ...>
);

Warning: Stateless function components cannot be given refs. Attempts to access this ref will fail.
Check the render method of `NumberInput`.

Uncaught TypeError: Cannot read property 'getInputNode' of undefined

Is this correct? I think the package should work with stateless components.
