Domokos,

Further to Brian's post, you need to install Control Handlers which 
respond to:

Class:                  Kind:

_kEventClassControl     _kEventControlValueFieldChanged
_kEventClassTextField   _kEventTextDidChange
_kEventClassTextInput   _kEventTextInputUnicodeForKeyEvent

This covers almost all situations where the text field will change, 
including changes by drag/drop of text from an external source such as a 
text clipping dragged over, text drag/drop from within the same field, 
as well as Paste from the contextual menu instead of the Edit menu.

Hope it helps,

Deep
