three js vertices does not update - dynamic

Question

I'm using three.js r67, and vertices does not seem to be updated.
I set geometry.dynamic = true, geometry.verticesNeedUpdate = true.
Circle is moving, but line is static....
Someone could help me?
var scene = new THREE.Scene();
var renderer = new THREE.WebGLRenderer();
var g = new THREE.CircleGeometry( 4, 16 );
var m = new THREE.MeshBasicMaterial({color: 0x114949});
var circle = new THREE.Mesh( g, m );
circle.position.x = 2;
circle.position.y = 2;
circle.position.z = -1;
scene.add( circle );
var material = new THREE.LineBasicMaterial({color: 0xDF4949, linewidth: 5});
var geometry = new THREE.Geometry();
geometry.vertices.push(new THREE.Vector3(0, 0, 0));
geometry.vertices.push(new THREE.Vector3(1, 1, 0));
geometry.verticesNeedUpdate = true;
geometry.dynamic = true;
var line = new THREE.Line(geometry, material);
scene.add(line);
var update = function() {
circle.position.x += 0.01;
line.geometry.vertices[0].x = circle.position.x;
};
var render = function() {
renderer.render(scene, camera);
};
var loop = function() {
update();
render();
requestAnimationFrame(loop, renderer.canvas);
};
loop();

Note: The legacy Geometry class has been replaced with the BufferGeometry class.
If you want to update the vertex positions of your BufferGeometry, you need to use a pattern like so:
mesh.geometry.attributes.position.array[ 0 ] += 0.01;
mesh.geometry.attributes.position.needsUpdate = true;
After rendering, you need to reset the needsUpdate flag to true every time the attribute values are changed.
