Massimo, in angularjs, if you want use Promises in all the application
scope, you need Factory o services, example :
var module = angular.module('myapp', []);
module.service('userService', function(){
this.api = $http.get('http://example.com/blog/default/index/blog.json');
});
// controller #1
module.controller('FooController', function($scope, userService){
$scope.data = userService.api.success(function(data) .etc.. );
});
// controller #2
module.controller('BarController', function($scope, userService){
$scope.my_scope = userService.api.success(function(data) .etc.. );
});

and data binding it's very easy... example :
<input type="text" ng-model="yourName" placeholder="Enter a name here">
<h1>Hello {{yourName}}!</h1>
