So if I understand you correctly, you don't want the button to be grayed out, but when the user clicks on it, you want it to do nothing?
I don't think that's good usability. Buttons which don't do anything are confusing to users. In my opinion it would be better to disable the button after the user clicks it once. That shows the user that there is no point in clicking it again.

I never suggested you should, I said change the behaviour of the button.

Then don't. This displaying of information is not some natural behaviour of HTML that you're fighting against, it's a behaviour you've implemented. Your code is what is "displaying this information once again below", add a condition to your code so it doesn't.
If you want help with your code then you'll have to post it, we can't guess what your code is.
You're adding a div or a span element on your ajax callback, I assume. In this case, just check if that div is already there, and if so, don't do the ajax call. Either that or replace the div instead of adding it.
Think about it. How would you do this? You can do it in a thousand ways.

I found a way to do it.
Calling the above code at the start of Jquery did the trick.
