Ethan, I don't think it's your typing, I think it's your timing. Looks like you're flipping your postTyper() when the combobox is changed, but that's not firing a new send() like the original blogger example did. Try changing your code so that changing the combobox triggers the send() and the send result="" handler triggers the postTyper(). That way you'll have the correct data in lastResult when you change your blogResult variable. That change should then be noticed by the bindings.
