How to change a defattr defined variable in an edit form in the fo/trigger :on-change ? I tried 2 different approaches - both are being triggered but the variable for "inactive-date" is not being set. a) apply-action:

fo/triggers {:on-change (fn [{::uism/keys [state-map] :as uism-env} form-ident key old-value new-value]
                                            (case key
                                              :member/active?
                                              (let [target-path (conj form-ident :member/inactive-date)]
                                                (when (not new-value) (uism/apply-action uism-env assoc-in target-path (datetime/now)))))
                                            ;; default
                                            uism-env)}

fo/triggers {:on-change (fn [{::uism/keys [state-map] :as uism-env} form-ident key old-value new-value]
                                            (case key
                                              :member/active?
                                              (when (not new-value) (uism/set-value! this state-map :member/inactive-date (datetime/now))))
                                            ;; default
                                            uism-env)}
