Coin mask, error without thousand, inputmask

Question

I’m using the inputmask plugin.

I have two cases, when I Seto 4.5 I expect the mask to appear 4.50 and when Seto 10000.5 I expect it to show me 10,000.50. But 4.5 shows me 40.50 , how do I show 4.50? Already the case of 10000.5 works correctly giving me 10,000.50.

Fiddle Aqui: https://jsfiddle.net/xs0rLfto/25/

$(document).ready(function(){
  $('.value').click(function(){
  	var dataValue= $(this).attr('data-value');
     $('#mask').val(dataValue);
  });
});

$('#mask').inputmask({
  digits: 2,
  digitsOptional: false,
  rightAlign: false,
  radixPoint: ",",
  groupSeparator: ".",
  alias: 'currency',
  prefix: " ",
  removeMaskOnSubmit: true,
  autoUnmask: true,
  numericInput: true
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p>Try to set 4.50 int into input value</p>

Currency : <input id="mask" type="text" />
<button class="value" data-value="4.5">
Set Value 4.50 Expect to be 4,50
</button>

<button class="value" data-value="10000.5">
Set Value 10000.50 Expect to be 10.000,50
</button>

• digits: 2,
• digitsOptional: false,
• rightAlign: ,
• radixPoint: ",",
• groupSeparator: ".",
• alias: 'currency',
• prefix: " ",
• removeMaskOnSubmit: true,
