How save changes of a editable list?

Hi everyone 

i have a code of a listview. You can add and elimitate items of the list. Also if you click on an item list this open a square. In this square you find a input text.


I need save all the changes that the user makes, i mean save the changes (add/ eliminate items) that the user makes to the default list view. and also save the text that the user write in each text input. The idea is that any user could edit their own listwiew. So if you open your list view the next time, you will have your list with all the changes that you make the last time. So each person have your own  and unique list.

How can i do that??? like a sign in system or account.or something like that?

i hope any of you can help me
Thanks everyone
