jQuery onChange: and onKeyPress:

> Hello,
> I would like to combine the use of onChange: and onKeyPress: to display
> 'Save' & 'Cancel' buttons.
>
> onChange: is useful when a value is pasted in to the text field, and
> onKeyPress: shows the buttons without having to click elsewhere. So far
> this is working well, except when the first component selected after
> entering text is the 'Save' or 'Cancel' button. When that happens, the
> onChange: action is triggered, which re-renders the button. From the
> user's perspective, the button press was ignored and needs to be done again.
>
> I would like to have the onKeyPress: action remove the onChange:
> behaviour.  How can that be done?
> Or is there a better way to detect that text was pasted in? (i.e. cases
> where onKeyPress: is not triggered).
>
> Here is some sample code...
> If you enter a value into the text input field and then press the
> button, you'll notice the ignored button press.
