What is the correct way to change coordinates with GeocodeModel?

import QtQuick 2.0
import QtLocation 5.12
import QtPositioning 5.12

Rectangle{

    // Icone que representa um marcador no mapa
    Image {
        id: ic_marker
        source: "qrc:///icons/icons/ic_map_marker.svg"
        sourceSize.width:  50
        sourceSize.height: 50
    }

    // Plugin responsavel por executar requisicoes de dados para o mapa
    Plugin{
        id: osm
        name: "osm"
        PluginParameter{name: "osm.useragent"; value: "TGAdmin"}
        PluginParameter{name: "osm.mapping.custom.host"; value: "https://tile.openstreetmap.org"}
        PluginParameter{name: "osm.mapping.providersrepository.disabled"; value: true}
    }

    // Marcador da posicao do tiro de guerra no mapa
    MapQuickItem{
        id: tgMarker
        anchorPoint.x: tgMarker.width / 4
        anchorPoint.y: tgMarker.height
        coordinate: QtPositioning.coordinate(latitude, longitude)
        sourceItem: ic_marker
    }

    Address{
        id: endeAtirador
        street: rua
    }

    GeocodeModel{

        id: geoModel
        plugin: osm
        autoUpdate: false

        onLocationsChanged: {

            if(count > 0){

                tgMarker.coordinate = get(0).coordinate

                query.addWaypoint(QtPositioning.coordinate(latitude, longitude))
                query.addWaypoint(get(0).coordinate)
                route.update()

                console.log("Coordenadas: ", get(0).coordinate)
            }

        }
    }

    Map{

       id: mapa
       zoomLevel: 17
       anchors.fill: parent
       center: QtPositioning.coordinate(latitude, longitude)
       plugin: osm

       RouteModel{

           id: route
           plugin: osm
           autoUpdate: false
           query: RouteQuery{id: query}

       }

       Component.onCompleted: {
           addMapItem(tgMarker)

           geoModel.query = endeAtirador
           geoModel.update()

       }

    }

}

I'm trying to create a route from one point to another, although it was getting the coordinates of the address I can not change the location of the other items with it
