Angular Js - LocalStorage

I'm new to Angular, I have a simple question to relay to LocalStorage in AngularJS. I have a json file to get data to the DOM and I already have the LocalStorage.getItem working and display on the console.

Right Now I need to figure out how to get that LocalStorage into the Dom after clicking a simple button.

This is my controller for the file:

angular.module('stock').controller('checkListController', [
    '$http',
    'checkListService',
    function checkListController($http, checkListService) {
        'use strict';

        var self = this;

        this.checkList = [];
        $http.get('api/checklist.json').then(function (result) {
            self.checkList = result.data.items;
        });

        this.checkListMissing = [];
        $http.get('api/checklist-missing.json').then(function (result) {
            self.checkListMissing = result.data.items;
        });


        var addList = [];
        var missingItemList = [];
        this.addItem = function (item) {
            addList.push(item);
            localStorage.setItem('item', JSON.stringify(addList));
            missingItemList = addList;
            console.log(missingItemList);
        }

    }
]);

Does this makes any sense? Thank you all
