Clicking Next doest not render new comments. Manual refresh works though. Why?

The route has:

queryParams: {
  page: {
    refreshModel: true
  }
},

model: function(params) {
  return this.store.findRecord('article', params.article_id);
},

setupController(controller, model) {
  let params = this.paramsFor(this.routeName);

  this.store.query('comment', { filter: { 'article-id': model.id }, page: { number: (params.page ? params.page : 1) } }).then(comments => {
    controller.set('comments', comments);
  })
}

Controller has:

queryParams: ['page'],
page: null,

And template:

{{#link-to “articles.show” model.id (query-params page=pageMeta.next) class="button -blue -mini"}}Next{{/link-to}}

Clicking on Next takes me to http://localhost:4099/articles/7?page=2, but the comments in the template are not refreshed. But when I manually refresh the page. The new comments are shown.

It seems like the query params in setupController isnt being updated. What could be going wrong here?
