NBT tag not changing

I did on player tick, for each slot of inventory of Event/target entity get contents copy as itemstack iterator

and set custom data number tag to add a nbt tag when ever the item is in inventory.

I check my item but it didn't add any nbt tags, is it because of its a content copy? if it is, then how do I apply to the real item in inventory?

If you give an item using "Add <count> <item> to <entity> inventory", follow these steps:

Create a local variable of type ItemStack (for example, current_item).
In the procedure, set this variable using "Set item stack <itemStack> to <item>".
Modify the NBT data using "Set custom data <dataType> tag <tagName> of <itemStack> to <dataVariable>".
Finally, give the item using "Add <count> <itemStack> to <entity> inventory".

Something like that:
