title: How to listen for and react to Ace Editor change events
body: <p>Can anyone please give an example, of how the on change event works in ACE Editor (<a href="https://ace.c9.io/#nav=api&amp;api=editor" rel="noreferrer">https://ace.c9.io/#nav=api&amp;api=editor</a>), with a simple <code>getValue()</code> when the there is an on change event and send the new text to a div? Would be much appreciated as there is no tutorials on how to use Ace Editor other than the documentation.
  Thanks</p>
