How to execute callback on page pop in Ionic 3?

I am trying to get some data from a page after it is dismissed. Since NavController.pop does not allow to specify any parameters, I am trying to use a callback.

Calling page code:

export class HomePage {

    constructor(
        private navCtrl: NavController,
        private articleService: ArticleService) {
    }

// this is called on second page's dismiss
onArticleFiltersDismissed(data: ArticleListFilterModel) {

    return new Promise((resolve, reject) => {
        if (!data) {
            console.log("No data from page ArticleFilterPage");
            return;
        }

        console.log("Dismissed page ArticleFilterPage with data ", data);
        console.log("This: ", this);

        // "this" does not points to a reference of this page 
        this.filterData = data;
        this.loadArticleBriefData(data);

        resolve();
    });
}        

// this shows the second Page and provides the callback as a parameter
onShowFilter(event: MouseEvent) {
    const filterPage = this.navCtrl.push(ArticleFilterPage, { filters: this.filterData, callback: this.onArticleFiltersDismissed });

}

private loadArticleBriefData(filters: ArticleListFilterModel) {
     // load data here
}

The second page (that is pushed over HomePage) code is the following:

export class ArticleFilterPage {

    dismiss(filter: ArticleListFilterModel) {

        this.callback(filter).then(() => {
            this.navCtrl.pop();
        });
    }

}

When ArticleFilterPage.dismiss function is called, it gets the correct input, but this points to a ArticleFilterPage reference instead of HomePage, so I receive the following error message:

ERROR Error: Uncaught (in promise): TypeError: _this.loadArticleBriefData is not a function TypeError: _this.loadArticleBriefData is not a function

Question: How can I properly transfer second page's data to the first page?

Note: I know that using a modal is more straightforward, but the second page already opens a modal and modal over modal does not seem to work properly (second modal's dismiss will also close the first one).
