Try echoing $value->acontentdetail->title stright out onto the page and see if the value is changing?
This sounds more like a caching issue than codeigniter.
You can add meta tags to tell the browser to not cache the page,
You other option would be to use jquery and use the onload event to clear the input. (this would be done when the page had finished loading, and $value->acontentdetail->title would also be cleared.
