How to disable ajax on each key press of inputtext control

Hi there, I have a problem with all my inputText controls.

I've put an ajaxstatus control  (from primefaces lib) and I can see now that on each key press an ajax request is sent to server.

I've tried with ajax="false" attribute but nothing happens.

I would like to disable this feature, I want the inputText only send its value on form submit.

How can I get it?

Thank you very much.
