Resetting the form does not work

Hi Patrick,

Resetting the form on the event page does not work. Autooptimize ist disabled
(EM-OSM Version: 1.8.5.1).
When you click on the link, the focus jumps upwards.
Javascript exists in the source text, but it does not work:

<td colspan="2">
	<em id="em-location-search-tip" style="display: none;"></em>
	<em id="em-location-reset" style="">Gespeicherte Veranstaltungsorte k?nnen hier nicht bearbeitet werden.<br><a href="#">Setze das Formular zurück, um einen Ort anzulegen oder suche erneut.</a></em>
</td>
</tr>
<!-- Show/hide the Search Address button -->
<script type="text/javascript">
jQuery(document).ready(function($){
	if( jQuery('#location-name').is('[readonly]') ) {
		jQuery('#osm-button').css("display", "none");
	}

	$('#location-name').change(function(){
		if( jQuery('#location-name').is('[readonly]') ) {
			jQuery('#osm-button').css("display", "none");
		}
		else {
			jQuery('#osm-button').css("display", "");
		}
	});
}).trigger('change');
jQuery('#em-location-reset a').click( function(){
	$('#osm-button').show();
});
</script>

What should I do?
Best regards
Frank
