Selected value (update form) on remote data of Selecte2?

1

I have problem with selected value (update form) on Select2 remote data

// I use in Meteor JS
// Template for update form
{{> afQuickField name='locationId' type="select2" options=defaultLocation select2Options=locationOptions value="0001"}}

// JS
updateTpl.helpers({
    defaultLocation: function () {
        return [
            {label: 'Cambodia', value: '0001 '}
        ]
    }
});


Template.registerHelper('locationOptions', function() {
    return {
        placeholder: "Search location",
        allowClear: true,
        minimumInputLength: 3,
        ajax: {
            data: function (params) {
                return params;
            },
            transport: function (args) {
                // Meteor method call
                Meteor.call('school_listAddress', args.data, function (err, results) {
                    if (err) {
                        args.error(err);
                        return;
                    }

                    args.success(results);
                });
            },
            results: function (data) {
                var results = [];
                _.each(data, function (result) {
                    results.push({
                        id: result.value,
                        text: result.label
                    });
                });

                return {results: results};
            }
        }
    };
});

It show error Option 'ajax' is not allowed for Select2 when attached to a <select> element..
