在ui路由器的状态之间共享ng模型数据

Question

I cannot seem to be able to get this form to update my model. It worked using ng-route but I decided to changed to ui-router as I wanted to nest templates.

I've tried a few things from here How do I share $scope data between states in angularjs ui-router? but no luck.

home.html

<form class="input-lg m-t m-l-n-xs hidden-lg hidden-md hidden-sm" role="search">
  <div class="form-group">
    <div class="input-group">
      <span class="input-group-btn">
        <button type="submit" class="btn btn-sm bg-white btn-icon rounded"><i class="fa fa-search"></i></button>
      </span>
      <input type="text" ng-model="searchQuery" ng-change="changeView('search')" class="form-control input-sm no-border rounded" placeholder="Search songs, albums...">
    </div>
  </div>
</form>

Controller

  angular.module('musica', ['ui.bootstrap', 'ngFacebook', 'spotify', 'cb.x2js', 'ngRoute', 'ui.router'])
   .config(function ( $facebookProvider, SpotifyProvider, $routeProvider, $httpProvider, $stateProvider, $urlRouterProvider) {

    $urlRouterProvider.otherwise("/");
    $stateProvider
        .state('login', {
        url: "/",
            templateUrl: "partials/login.html",
        }).state('home', {
            templateUrl: "partials/home.html",
        }).state('home.select', {
        templateUrl: "partials/home.select.html"
        }).state('home.search', {
            templateUrl: "partials/home.search.html",
        }).state('home.queue', {
        templateUrl: "partials/home.queue.html"
        }).state('join', {
        templateUrl: "partials/join.html"
        }).state('creating', {
        templateUrl: "partials/creating_venue.html"
        }).state('home.server', {
        templateUrl: "partials/home.server.html"
        })

})

.controller( 'DemoCtrl', ['$scope','$rootScope', '$location', '$facebook', 'Spotify', 'x2js', '$http', '$state', 'globalStore', function ($scope, $rootScope, $location, $facebook, Spotify, x2js, $http, $state, globalStore) {

$scope.searchQuery='hello';

$scope.changeView = function(view){
        if(!$state.is('home.search'))
        {
            $state.go('home.search');
        } 
        $scope.searchTrack();
    };

$scope.searchTrack = function () {
    console.log('searching ' + $scope.searchQuery.query);
    Spotify.search(this.searchQuery.query, 'track').then(function (data) {
        $scope.tracks = data.tracks.items;
    });
};

If I then type in the search box all I get is hello and not the updated value. I thought that since I don't mention controllers in the state provider that only one controller would be instantiated. I would really like to know what is going on. Thank you very much.

One think with $scope sharing is - we need a reference , not valueType .

So, if we want to share data among 'home' hierarchy family... the home controller just should introduce Model = {}

.state('home', {
    templateUrl: "partials/home.html",
    controller: function($scope){ $scope.Model = {}},
    ...

And later we can use that to share data

$scope.Model.searchQuery = 'hello';

And

<input type="text" ng-model="Model.searchQuery" ...
