Qt Map create Multiple Polylines ( Not linked to each other )

[Mohamad Ayrot]

iam tryin to create multiple polylines on the map, but should not be linked to each other.
i used ListModel and MapItemView as follows:

  ListModel{
            id: linesModel
        }

  MapItemView {
            id: lineModelView
            model: linesModel
            delegate: MapPolyline {
                line.width: 3
                line.color: "red"
                path: model.path
            }
   }

with mouse click i put the points on the map into array

property var polyCoords : []

onClicked(){
var point =  map.toCoordinate(Qt.point(mouse.x,mouse.y));
         
  polyCoords.push(point)
}

then i handle key click Key_P to put points into lines model:

if(event.key === Qt.Key_P){
  console.log(polyCoords)
 var newLine = { "path": polyCoords }
 linesModel.append(newLine)
        
  }

but the polyline does not appear on the map, what should i do in this case ?
