Help! about onChange:'submit()'

Hi, All
I have many select lists like this:

                        html select
                                list: self list;
                                onChange: 'submit()';
                                selected: self selected;
                                labels: [ :value | value name ];
                                callback: [ :value | self selected: value ].

this runs on localhost:8080 well.

but when deployment on (eg.192.168.1.4);

submit does not work. the URL no response.

Could anyone give me a hint?

Thanks for your help!
