Use Update for HIbernate in a form Primefaces

0

I have an Xhtml page with a DataTable and within that Datatable has a list with the result of items that came from the Database, one of the columns has a button called edit where it opens a form with input'se that inputs are filled with the data, but clicking save data is not modified. In the console the update values are '?'. Everything is triggered however the values are not received and sent.
