                                    return { name: "No Results." }
                                } else {

I suspect it's not working because:
on("keydown.autocomplete", ...)

Isn't a valid jQuery event. I think you mean to use "keydown" instead. However that's not the only problem, you're calling the autocomplete() function inside the event handler, but you actually only need to call it once when the document is ready. The autocomplete() function has a property called minLength which you can set to restrict auto-completion.

Remove the keydown event handler and call autocomplete() directly, and provide the minLength property to restrict it.

I have remove this it's not working.http://jsfiddle.net/uuPGq/ i have use this with static data it's working

"it's not working" isn't enough to go off of, we need more information on what exactly isn't working. Have you checked the browser console to see what the error is? What is the error you're receiving? Or is it just not triggering?

I have use key up and down for set value in input box but not set.This is major issue

You've not answered the questions I posed in my previous comment though. You say the up and down key events aren't working but you're providing no context. You need to check the browser console and look for potential errors, you may even need to debug the JS file to step through the code to see what isn't working.

Remember that we can't see your screen or the output of your code, so you need to do some work to identify what the new problem is.
