title: Enter key event handler on react-bootstrap Input component
body: <p>I have an <code>Input</code> component with a button (<code>buttonAfter</code> property), I set an <code>onClick</code> handler associated to the button and so user can type some text and clic the button to fire the right action. </p>
  
  <p>However, I would like user to be able to press <code>[Enter]</code> key (keycode 13) to achieve the same effect as clicking on the button, just to make the UI easier to use.</p>
  
  <p>I could not find a way to do it, of course I tried <code>onKeydown</code> to register an handler for key down event but it is just ignored.</p>
