Answer 1

You can use this approach as well:

let something = { test: 1 };
this.nav.push(existingPaymentModal, {something});

and than

constructor(private navParams: NavParams) {
        this.something = this.navParams.get("something");
 }

Answer 2

Use the NavController to pass data to the Page as you navigate to it:

this.nav.push(PlacesListPage, {
    xxx: this.data
});

Then use NavParams in your PlacesListPage to access the data:

constructor(navParams) {
    this.xxx = navParams.data.xxx;
}
