The rules work and the messages don't work

The rules work and the messages don't work

Hello,
I have a problem with the validation messages in jQuery. I have a dynamic form, I put rules (rules) for field 'tel_m' and it works well for all the fields (dynamic). Now I would write 'messages', the problem is that the validation does not work very well: it is enough for me to write a single field correctly (not vacuum telling figures) and the form is submitted WITHOUT than other fields are valid. Where is the mistake?
EDIT:
  1. $ ('input.comment'). each (function () {
                     $ (this) .rules ("add"
                         {
                            required: true,
                            digits: true,
                            messages {
                                  required: "Please enter a phone number",
                                  digits: "Please enter numbers",
                                            }
                         });
    });
