Parameters were passed to method 'onSearchStart'

We need to add extra parameter to search criteria:

        $('#Origin_Value').autocomplete({
            serviceUrl: '/Rate/FindCity',
            deferRequestBy: 300,
            minChars: 3,
            maxHeight: 250,
            width: 161,
            zIndex: 9999,
            onSelect: onOriginChanged,
            onSearchStart: function (context) {
                context['countryId'] = 1;
            }
        });
