escaping quotes when updating db

[eluser]murichej[/eluser]
hi, i have one problem..

I get data from form and save them to database with jquery ajax. Everything works fine but the codeigniter is escaping quotes by itself.

I'm using jquery $.ajax (post method) to call controller wich calls model that updates data.
