Providing the data has been saved to the database and an id exist,
couldn't you use something like
<t:ActionLink t:="yourId" context="person.id"
t:zone="someZone">Button</t:ActionLink> next to your remove action.
Then in the backend create an event handler for your action,
Object onActionFromYourId(Person person) {
//do something
return someZone.getBody();
}
Lastly, process zone in the interface.
Not sure if that helps.
