Close() into function using ScriptUI.

Question

Guys, I created an interface with ScriptUI that has a iconbutton within a group, which in turn is inside another group. I also created a listener to see which pressed on the keyboard, which performs a function where there is a condition that should close the interface if the key is pressed "Enter." However there is an error on line # 23, I am unable to set the correct path .... I'm even embarrassed to ask, but I'm more than an hour trying and I can not solve this. The onClick event on line # 12 runs correctly kicking the groups using "parent", but how do I need to walk the line as # 23?
Very Thanks
dialogo();
function dialogo(){
            var janela = new Window ("dialog");
                        var grupoDaDireita = janela.add ("group");
                                    var grupo4Dir = grupoDaDireita.add ("group");
                                    var btnOK = File (Folder(File($.fileName).parent).fullName+"/"+"ok_btn.png")
                                    var eventoOk = grupo4Dir.add ("iconbutton", undefined, btnOK, {style: "toolbutton"});
                                    eventoOk.onClick = function (){this.parent.parent.parent.close();};
            janela.addEventListener ("keydown", function (k) {verificaKeyboard(k);});
            janela.show ();
function verificaKeyboard(k){
            alert(k.keyName);
            if(k.keyName == "Enter"){
                        janela.close();

Hi,
move your function verificaKeyboard() into body of function dialogo()
variable "janela" is local and can not be accessed.
