Q: Adding and deleting items from a sortable ordered list causes problems in numbering the items I have sortable ordered list with a few items. 
Each item in that list can be deleted and/or moved and I can dynamically add more new items.
All works fine as long as I do not add a new item and delete one of the existing one. 
Example: 
I run the code and get a list


*

*ABC

*CDE

*EFG

*GHI

*IJK


I delete "3.", so item "4." moves up and is now "3." on that list, while "5." ist now no "4."
So far so good.
If I add a new item it will be added at the end of the list as no "6.", "7." and so on.
But as soon as I delete or add any item I am running into problems with the numbering of the list items. I suddently have a list looking like that
e.g.
1. ABC
3. EFG
3. GHI
4. IJK
The numbering is no longer correct.
What can I do to prevent this from happening!?
