Radios / Checkboxes not included in modified / changed condition method.

[Byte-Lab]

It looks like radio and checkbox inputs are not included in a changed / modified trigger or condition callback. This is my current setup:

$("form").autosave({
            callbacks: {
                // Every 10 seconds, perform an autosave
                trigger: {
                    method: "interval",
                    options: {
                        interval: 10000
                    }
                },
                condition: "modified",
                save: function(options, formData) {
                    // Add AJAX spinner
                    $ajaxSavingBlock.show();
                    $.ajax({
                        url: "{{ ajax_url|raw }}",
                        data: formData,
                        dataType: "json",
                        type: 'POST',
                        success: function(data, testStatus, jqXHR) {
                            // Get rid of spinning autosave AJAX visual:
                            $(this).next("save");
                            $ajaxSavingBlock.hide();
                        },
                        error: function(jgXHR, textStatus, errorThrown) {
                            $ajaxSavingBlock.hide();
                        }
                    });

                    // Notify jQuery autosave that the AJAX call is finished
                    return false;
                }
            }
});

Changing a radio button or checkbox value does not cause the save function to get fired. Changing an input text field does. Any ideas as to how to fix this?
