I update topic using custom controller where function was triggered through ajax. Client side code gets back result with a changed topic title but I’m unable to figure out how to refresh topic title in topic-view inside “then” callback. Strangely the archieved property change will call archieved “lock” icon to show up. Title will change only in page title but not in topic main title.
```
export default {
actions: {
clickSoldButton(topic) {
ajax("/topic/sold", {
type: "PUT",
data: {
topic_id: topic.id
}
}).then((result) => {
topic.set('custom_fields.sold_at', result.topic.sold_at);
topic.set('title', result.topic.title);
topic.set('archived', result.topic.archived);
}).catch(() => {
bootbox.alert(I18n.t('topic_trading.error_while_marked_as_sold'));
});
}
}
};
```
Is there a certain way to get Title to change other than navigating to topic or page reload?

There is a new event for this you can use after
[https://github.com/discourse/discourse/commit/f8a31d927f35e1302ec4788b8a430667f703f59a](https://github.com/discourse/discourse/commit/f8a31d927f35e1302ec4788b8a430667f703f59a)
`this.appEvents.trigger('header:update-topic', topic);`
Also, if you properly use `PostRevisor` this is handled automatically for you.

Thank you. But I can’t use PostRevisor as I want topic to be updated even when it’s not editable by user. As I understand, revisor will go through Topic.update which prevents changes after editing time has passed?

Not really a problem, cause you can disable validations when you update if you wish via the api (or perform the edit as system)

Ok. I’ll give it a try. Thanks!
