Mengapakah nilai pilihan kotak pilihan Negeri tidak betul dalam borang edit jqGrid saya?

<code class="javascript">var countries = { '1': 'US', '2': 'UK' };
var states = { '1': 'Alabama', '2': 'California', '3': 'Florida', '4': 'Hawaii', '5': 'London', '6': 'Oxford' };
var statesOfCountry = {
    1: { '1': 'Alabama', '2': 'California', '3': 'Florida', '4': 'Hawaii' },
    2: { '5': 'London', '6': 'Oxford' }
};

var resetStatesValues = function () {
    grid.setColProp('State', { editoptions: { value: states} });
};

$("#list").jqGrid({
    data: mydata,
    datatype: 'local',
    colModel: [
        { name: 'Name', width: 200 },
