Not working with dymamic load into the table

[salfredogonzalez]

Hello, I would like a little assistance on how can I solve this issue. I am working into a Master-Detail form to load some products into a form, so I select and add a product and append it to the table. So far, so good, but then when I click the button to edit is not working, only when the table has information when the page loads.
