Error on writeRequested

When I tried to write a response to the idle channel it writes the first
time then the idletimer continues to run and it still detect that the
channel is idle even though I wrote a response on it.  What do I need to do
for it to change its state,  I think the error is in there that's why it is
saying that I cannot send more response than the request
