title: react: how to set focus from a click handler
body: <p>My react-redux based form has a button that should reset the form <em>and</em> move focus back to the first input field.<br>
  Resetting the content is straight up redux state, but I'm having trouble with the focus. </p>
  
  <p>autoFocus on the first field works only on the initial render.  Is there any sane way to re-trigger it?</p>
  
  <p>If I need to go with explicit element.focus(), where should I call it from? I'm using react-redux, but not redux-forms.</p>
