How to clear an event

Question

I am creating a comment system with reply only that at the time of reply goes twice to the bank when I send a comment, I made the system of response in slide where you open one and close the other, only when you open the next one to comment and close the previous one is still loaded and counts as if it were two answers someone knows how to solve ?

code

    function addEventosRespostas() {
        $(document).on("click", ".resposta", function(){
            var id = $(this).children('input').val();

            $('.coment').find('.resp').fadeOut("slow");
            $(this).parents('.coment').find('.resp').fadeIn("slow");

            $(document).on("submit","form", function() {

                var texto = $(this).children('textarea').val();
                var coment_id = $(this).find('#id_coment').val();
                var id_user_coment = $(this).find('#id_user_coment').val();

                    $.post('swith/viwer.php',{
                        acao: 'resposta', texto: texto, coment_id: coment_id, id_user_coment: id_user_coment},
                            function(){
                                $('.dialog').fadeIn();
                                $('form textarea').val("");
                                $('form input[type = submit]').val("responder");
                                $('.closemodal').click(function(){
                                        $('.dialog').fadeOut();
                                });
                            });
            return false;
            });

        });
    }

Answer 1

This is happening because you add the event:

 $(document).on("submit","form",function());

twice, so if a form der Ubmit it will fall in both understand? I made an example where you will clearly see this happening.

Example

A solution would only be to add the code one time :

 $(document).on("submit","form",function());

So you’ll get all the "form" submits. I hope I have helped, in case you have any doubts or need me to explain you better can comment below.
