title: Add text literal to jquery input mask
body: <p>I'm using <a href="https://github.com/RobinHerbots/jquery.inputmask" rel="nofollow">jQuery Input Mask</a> and I'm setting a mask using <code>data-inputmask="'alias': 'integer', 'radixPoint': ',', 'rightAlign': false, 'allowMinus': false, 'allowPlus': false, 'autoGroup': true, 'groupSeparator': '.', 'autoUnmask': true"</code></p>
  
  <p>I want to add the text literal "km" after the value so the mask will be something like <code>15.000 km</code></p>
  
  <p>How can I do that? Is it possible to do it using just the data-inputmask attribute? </p>
