How to allow a ItemRenderer to take user input?

[Brendan cheng]

HI,
I built a ListView with customized ItemRenderer.  In the ItemRender, I have a 
TextInput field and I want to make it Editable and be able to take user input 
and change the list.
I set it TextIput component to Editable but it doesn't seem working.
Could you give me some direction?
I also want to take the user input and bring them to server side too.   I want 
to make the list dynamically synchronized with server data and user input.  is 
it too much to ask?
