Clearing an event

I'm creating a comment system with a response only when it's time to respond twice to the bank when I send a comment, I did the slide response system where you open one and close the other, only when the next one opens to comment and close the previous one is still loaded and counts as if it were two answers does anyone know 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;
            });

        });
    }

// Exibir mais comentários



    $('#load').on("click",function(){

        loadmo = $(this);
        var video = $('#link').val();
        var numcom = $('.comentar .com').length;

        $.post('swith/viwer.php',{
            acao:'comentarios', video: video, numcom: numcom},function(contcom){

            if(contcom => 1){
                $.post('swith/viwer.php',{
                    acao:'morecoment', video: video, numcom: numcom},function(morecom){

                    $('.comentar .com:last').after(morecom);
                    $('.comentar .com').fadeIn("slow");
                    addEventosRespostas();





                }); 

            }

            if(contcom > 1){

            }else{
               loadmo.fadeOut("fast"); 
            }
