[jQuery] Child ID

[shapper]

Hello,

I have the following:

  $("#StartDate, #FinishDate").each(function() {
    $(this).mask("9999-99-99 99:99:99");
  });

It is working but I want to apply this only to StartDate and
FinishDate inputs that are inside the form with id "Create".

How can I do this?

Thanks.
Miguel
