Please follow the steps in the referenced technote and if you can't find the issue then post details of what you found and the returned JSON. Sounds like maybe your JSON response doesn't have an Id data object.

Why are you putting data you already have stored locally in a hidden textbox?

agg9505

@kthorngren yes, the JSON have the Id value

I have found the problem, in a function where I can have a undefined value, I have to return the value, which I have commented in the function xD

Ah yes - the columns.render, if defined, must return something. Well found.
