Change 3D model file after click button

Hello everyone :wave:

I’am pretty new in Babylon and i have one problem. I want to change 3d model file when click button my button:

<button onclick="changeModel('prostokat.babylon')">test</button>

Function changeModel

var modelName = "kolo.babylon";

    function changeModel(renameModel){
       modelName = "untitled.babylon";


function delayCreateScene() {
  var scene = new BABYLON.Scene(engine);
  var camera = new BABYLON.ArcRotateCamera("Camera", 0, 0, 0, new BABYLON.Vector3(0, 0, 0), scene);
  BABYLON.SceneLoader.Append("", modelName, scene, function 
  (meshes) {

If i click on the button, my function run but model is not replaced :expressionless:

This is because you are creating a new scene instead of adding to your current one
