Updating "tr" data in laravel

I'm facing difficulty in doing this task : - I have a table that have an add delete , update buttons for every single row I've done the add and delete thing by adding data-attribute for each button according to the row's data Id. It works perfectly for deleting and inserting elements. Yet i can't find a way to update every single row so i need help !

Note: I'm updating my elements using Ajax.

Any strategy ? i can post a screenshot for my code/view cause it is a bit too long .
