Description of problem:

An input that is watched for changes on a certain interval (as opposed to fields that react on the change event) sends multiple requests on every single change, if that fields has been focused (entered) more than once.

If you just enter it and press a letter, it will send 1 request and will continue to do so for every letter if types slowly enough. However, after leaving this field and entering it again, every letter will send 2 requests, and so forth.
