After searching, the edit item takes previous value, whats wrong? - primefaces

Question

I have done a dataTableFilter to create edit and delete items with search. Everything works fine until I do "Search as you Type", but when I add an item after doing a "Search as you type", the item is added in the database and the view, but if I click edit aginst it, it shows the values below it and when I press cancel, the added value disappears ! Again if I do search as you type the new item starts appearing.
I have been struggling with this for long, are there limitations in JSF primefaces ?
