text fields with events

Hello,
I'm trying to create CF 6 text fields with events. But I probably do not do it right.
I oriented myself to the article in the FAQ "How to use the Fields Events".
In the text field with the ID "geloc3" I have in Extra attributes:
class: leaflet-locpicker
Under "Events":
on change
Action: Function
Elements identifier: #latitude AND #longitude
​
Then comes a Javascript:
$ ( '# Geoloc3'). LeafletLocationPicker ({
locationSep: '-'
})
.on ('show', function (e) {
$ (this) .siblings ('em'). text ('click on map for insert the location');
})
.on ('hide', function (e) {
$ (This) .siblings ('em') text ('.');
})
.on ('changeLocation', function (e) {
$ (This)
.siblings ('# geolat'). val (e.latlng.lat)
.siblings ('# geolng'). val (e.latlng.lng)
.siblings ('i') text ('"' + e.location + ''. ');
});
​
Then 2 text fields in which data should be displayed
Text field with ID "geolat"
Text field with ID "geolng"
​
It only appears to me in the text box with the class "leaflet-locpicker".
​
Wat is the problem....
​
Many Thanxs
F.
