How do i asynchronously write binary files?

Question

Hi
I'm sure I'm missing something obvious here but I cant see
what's wrong with my code. I'm trying to save a file using
asynchronous methods but for some reason the function
onCompleteFunc is not being called. Any ideas what I'm doing wrong?
function testSaving(fileObj, binaryData, onSuccessFunc,
onErrorFunc){
var onCompleteFunc = function(event){
try {
stream.writeBytes(binaryData, 0, binaryData.length);
catch (fileError) {
onIoErrorFunc();
stream.close();
onSuccessFunc();
var onIoErrorFunc = function(event){
stream.close();
onErrorFunc(event);
var stream = new air.FileStream();
stream.addEventListener(air.Event.COMPLETE, onCompleteFunc);
stream.addEventListener(air.IOErrorEvent.IO_ERROR,
onIoErrorFunc);
stream.openAsync(fileObj, air.FileMode.WRITE);
}

FileStream dispatches a COMPLETE event when the end of the
file is reached during an asynchronous read. When you're writing
asynchronously, you don't need to wait for any events to start
writing.
When you're done writing, call close() and then wait for the
CLOSE event, which signals that all data has been written to the
file.
