         * `transformResult`: `function(response) {}` called after the result of the query is ready. Converts the result into response.suggestions format.
 		* `autoSelectFirst`: if set to `true`, first item will be selected when showing suggestions. Default value `false`.
 		* `appendTo`: container where suggestions will be appended. Default value `body`. Can be jQuery object, selector or html element. Make sure to set `position: absolute` or `position: relative` for that element.
+    * `dataType`: type of data returned from server. Either 'text' (default) or 'jsonp', which will cause the autocomplete to use jsonp. You may return a json object in your callback when using jsonp.
