I suspect that numberOfDaysToAdd is a string... then if, for example, someDate.getDate() is 27 and numberOfDaysToAdd is "5", then someDate.getDate() + numberOfDaysToAdd) will be "275" rather than 32.

Parse the value to an integer before adding it up to the getDate() return value:

JavaScript

var numberOfDaysToAdd = parseInt($(this).val(), 10);
if (isNaN(numberOfDaysToAdd)) {
  // invalid number; show an error message
  return;
}
// continue with the calculations
