Hello, good afternoon!

Follow an example I did to try to help you.

$('#ativacao')[0].valueAsDate = new Date();

$('#ativacao').change(function() {
  var data = this.valueAsDate;
  
  data.setDate(parseInt(data.getDate()) + parseInt($('#dias').val()));
  
  $('#vencimento')[0].valueAsDate = data;
  
});

$("#executar").click(function(){
    $('#ativacao').change();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


   <input type="number" id="dias" placeholder="dias" />
   <input type="date" id="ativacao" />
   <input type="date" id="vencimento" />
   <input type="button" id="executar" value="Executar" />
