I used this:

    cancelAnimationFrame(this.id);// Stop the animation

    this.renderer.domElement.addEventListener('dblclick', null, false); //remove listener to render

    this.scene = null;

    this.projector = null;

    this.camera = null;

    this.controls = null;

    empty(this.modelContainer);

The method empty is a substitute to jQuery empty, you can use it:

function empty(elem) {

    while (elem.lastChild) elem.removeChild(elem.lastChild);

}
