ember-leaflet drag point to latlng - ember.js

Question

on my polygon 'dragend' function i get the new position via (e.target._newPos) that represents the position on my layer.
But when i convert that point as follows:
let containerPoint = layer._map.layerPointToContainerPoint(e.target._newPos);
let latlng = layer._map.containerPointToLatLng(containerPoint);
i get some coordinates that's what i want. But when i try to present them on my leaflet map layer an zoomin or out that point jumps on my map so wtf is going on?
import PolygonLayer from 'ember-leaflet/components/polygon-layer';
.
.
.
draggable.on('dragend', (e) => {
let containerPoint = layer._map.layerPointToContainerPoint(e.target._newPos);
let latlng = layer._map.containerPointToLatLng(containerPoint);
let dragEnd = this.get('onDragEnd');
dragEnd(latlng);
});

Answer 1

In my template i have a presentation of a map
items: {},
i have a item component
didRender() {
let layer = this.get('_layer');
let path = layer && layer._path;
if (!path) {
return;
}
let draggable = new L.Draggable(path);
draggable.enable();
draggable.on('dragend', (e) => {
let containerPoint = layer._map.layerPointToContainerPoint(e.target._newPos);
let latlng = layer._map.containerPointToLatLng(containerPoint);
let dragEnd = this.get('onDragEnd');
dragEnd(latlng);
});
},
so onDragEnd i will update the dragged items position with new latlngs but after my update the item is jumping on map
