How to use javascript to display marker for an address?

I have a map inside a Confluence wiki page, and using PocketQuery I get the addresses I want to display from my DB.

What's the most direct way to do the Nominatim request and the Leaflet marker placement?

I can generate code that looks like this:

    <script>
    #foreach($person in $result)
    $.getJSON('https://nominatim.openstreetmap.org/search/$person.strasse $person.hausnummer ,$person.plz?format=json', cbMarker);
    function cbMarker(data){
      L.marker([data.lat, data.lon], {title: '$person.name'}).addTo(map);
    }
    #end
    </script>

but something is wrong, it seems to crash the template and it falls back to just showing me $result as a table.
