Alright, here’s one more update on this. I think I maybe on to the reason why `api.onPageChange` does not work for topic pages and the answer might be this:

> [@zogstrip](#):

With that in mind here’s the new way I settled on for firing a script once a user enters a topic page and doing a bit of clean up after leaving the topic page. This could still be improved I suppose but for now will only fire once when entering a topic and once when leaving.

```plaintext
const TopicRoute = require('discourse/routes/topic').default;

TopicRoute.reopen({
	activate: function() {
		this._super();
		Em.run.next(function() {
		// do stuff here when a topic page is opend
		});
	},
	deactivate: function() {
		this._super();
		// clean up here when leaving the topic page
	}
});

```

As far as I tested, this will both log stuff to the console and ~~work with jQuery.~~ **edit: Nope. Again 😅**

If anyone is interested in the breadcrumbs I came accross to put this together check these posts / topics out:

Once I figure out how to fire a script once every time the post stream is updated I will post another update here.
