Hi @sasule, I've opened a fix in #1272. The root cause was that click listeners were attached directly to confirm elements at init time — after AJAX snippet updates, those elements are replaced with fresh DOM nodes and the listeners were lost. The fix uses event delegation on the datagrid container instead, which survives snippet updates.

Could you test the PR branch and confirm it resolves the issue for you? Thanks!
