I want to get this:

$('input#form1').live("change", .....

Can anybody help me? thx

The reason is your return false.

This will work:

$('#form1').live("click change", function() {
        $.ajax({
        type    : "POST",
        cache    : false,
        url        : "berechnung_ajax.php",
        data    : $(this).serializeArray(),
        success : function(data) {
                        $('#berechnung').html(data);
        }});

    return true; // return true in order not to prevent the event
    });    
});
