Inserting records manually into an exisiting sqlite file present in project through sqlite browser is not showing up?

I already have a sqlite file within the project with pre-populated values in it. The app is in the app store.Now, I need to do a new release and for that I need to pre populate some new values into sqlite file. I tried manually opening the sqlite file present in the project and added new records using sqlite browser. when i install the new app(ipa) over the existing app(ipa), the new records I added is not showing up. When i uninstall the old app(ipa) and install the new app(ipa) the records are showing up. can anyone let me know me how solve the problem?
