Canvas drag and drop with touch

I created drag and drop but touchstart don't work.

var cl = this.cl;
createjs.Touch.enable(stage);
cl.addEventListener("touchstart", onTouch.bind(cl));
function onTouch(e) {
  thisCl.addChild(activeCl);
  canvas.addEventListener('touchmove', moveTouch);
  canvas.addEventListener("touchend", mUp);
}
function mUp() {
  canvas.removeEventListener('mousemove', move);
  canvas.addEventListener('touchmove', moveTouch);
}
function move() {
  cl.x = stage.mouseX;
  cl.y = stage.mouseY;
}
