Creating a Favorite page - Clicking a button to add elements to another page

For an Ionic app project, I created a json file that stores some event data. This file will later be downloaded within the application and stored locally on the device/ but might be updated to provide new data.

I displayed the data on the artist page with a ng-repeat directive. The problem I am facing is the following: Everytime when the user clicks the plus button on one of the elements, the element is supposed to be displayed on another page (kind of favorite page). What can be a solution to this problem?

HTML

  <ion-item
          ng-repeat='item in artists | filter: query' class="artist-box">
              <div class ="info-box-purple" >
                  <div class = "info-box-text">
                      <span>{{item.day | Saturday}}<br>{{item.time}}<br>{{item.stage}}</span>
                  </div>
              </div>
              <a href="#/app/artists/{{item.shortname}}">
                  <h3 class="artist-title"><span>{{item.name}}</span></h3>
                  <div class="item image item-image">
                      <img ng-src="img/artists/{{item.shortname}}.jpg" alt="{{item.name}} Photo"/>
                  </div>
              </a>
              <div><button class="add-button button button-royal ion-plus"></button></div>

          </ion-item>

Controller (link between html and controller on separate page)

   .controller('ListController', ['$scope', '$http', '$state', function($scope, $http, $state){
        $http.get('js/data.json').success(function(data) {
            $scope.artists = data;
            $scope.pickedartist = $state.params.bandId;
        });
    }
])
