AJAX is not working

Does anyone know why this AJAX is not working? The variables are receiving the values, only the part of sending the data to actualiza.php does not 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);
                });      

        });
