Seems like you're doing other way around?

if the input type is empty or null that is where you want to disable the datecalendar is it?

$('#number').keyup(function() {
   if ($(this).val() == '') {
   alert("triggered"); //Placed this to make sure it works.
    $('#calenderdate').prop('disabled', 'disabled');
    $("#calenderdate").removeClass(".datepicker, .gj-textbox-md");
    $('#calenderdate').prop('disabled', true);
   } else {
    $('#calenderdate').prop('disabled', false);
    $('#calenderdate').val('');
   }
 });

If the selected value is false ie ($this.(val() == '') {...} then make the input value as true .

$('#calenderdate').keyup(function() {
      if ($(this).val() == '') {
     $('#number').prop('disabled', true);
    } else {
     $('#number').prop('disabled', false);
    }
  });
