Be sure to check the box labeled "Continuously Updates Value" in the
bindings inspector panel for the text field. Without that, the new
value gets sent only when editing is ended by tabbing out of the
field, pressing the return/enter key, or otherwise sending focus to
some other part of the interface like when you click on the table.
Of course, if you do this, your undo mechanism can get ugly, since
every keystroke then becomes a change.
So if you have a text field that currently contains the number 200
and the user wants to change this to 1024, each of the four
characters will result in a new undo action, so after entering 1024
they decide to undo, well, it goes back to 102. A second time brings
it back to 10, a third time to 1, and finally the fourth time brings
it back 200 (which is what they probably expected).
