How to change height of 3DModels?

You can use Matrix4.multiplyByPoint to multiply x,y,z of cartesian3 as given below:

Cesium.knockout
  .getObservable(viewModel, "height")
  .subscribe(function (height) {
    height = Number(height);
    if (isNaN(height)) {
      return;
    }
console.log(entity,"entity");
    const cartographic = Cesium.Cartographic.fromCartesian(
     entity._position._value 
    );
    const surface = Cesium.Cartesian3.fromRadians(
      cartographic.longitude,
      cartographic.latitude,
      0.0
    );
    var newHpos = Cesium.Matrix4.multiplyByPoint(Cesium.Transforms.eastNorthUpToFixedFrame(surface),
                new Cesium.Cartesian3(0, 0, height), new Cesium.Cartesian3());
    entity.position.setValue(newHpos);
  });

Here is the working sandcastle example.
