InDesign CC addEventListener not work

Don't work in InDesignCC addEventListener:

var w =new Window ("dialog");

var b = w.add ("listbox", undefined, "Qwerty");

b.addEventListener("click", function (k){

    alert("detail: "+k.detail+'\r'+"X: "+ k.clientX+'\r'+"Y: "+ k.clientY);

});

w.show ();

it's ok to work in ESTK and CS.
