Insert data from page to other page

Hello all,

I have a listpage which I can fill with items by a insert input field on that same page. Also I have a page which have many items and I want that when I click on a button that is by an item the title is inserted in the list on the listPage. What is the simplest to do that?

I thought that something like this.navCtrl.push was good enough but then I only go to that page but see no item inserted in the list
