jQuery Grid Plugin - jqGrid

I need to replace the editoptions values for column Geography. I am passing an string into userdata formated correctly. Where do I add

beforeInitData: function(formId) {
                            jQuery("#list").setColProp('Geography', { editoptions: { value: jQuery("#list").getGridParam('userData')[0]} });
                        }

in the code below? thanks
