AJAX is not working

Question

Does anyone know why this AJAX isn’t it working? The variables are receiving the values, only the part of sending the data to actualiza.php is that it doesn’t work.

$("#btnedit").click(function(){
        var proc=$("#procedit").val();
        var nome=$("#nomeedit").val();  
        var cc=$("#ccedit").val();
        var data_nasc=$("#data_nascedit").val();

        alert(proc);
        alert(nome);
        alert(cc);
        alert(data_nasc);

            $.post("actualiza.php",{ proc: proc, nome: nome, cc: cc, data_nasc: data_nasc },
                function(data)
                {
                        $("html").html(data);
                });      

        });
