$rootScope.app is Undefined

Question

People,

I asked for help to rescue the value of a variable in a js file by the $rootScope that is in the controller of my application. My intention is to rescue in the page hmtl this attribute to be able to display on the screen the system version.

When running the application the message occurs: $rootScope.app is Undefined

infoBuild

var VERSAO_SISTEMA = '01.02.00.002'; 

Controller

angular.module('webapp') . controller('Imrcontroller'',

    function ($scope, $rootScope, $translate, $http, $timeout, Log, WebServiceX, Alert, Analytics, Error, Utils, WebServiceRest, WebServiceT) {

    Log.debug("ImrController()");
    Analytics.trackEvent('controller','ImrController');
    $scope.container = {};     
    $rootScope.currentview.id = 'iMR';
    $rootScope.currentview.group = 'IMR';
    $rootScope.currentview.title = 'IMR';
    $rootScope.currentview.icon = 'fa-list-alt';
    $rootScope.currentview.locked = false;
    $rootScope.currentview.menu = true;
    $rootScope.currentview.description = 'IMR';
    $rootScope.app.version.id= VERSAO_SISTEMA;

    //Preenchimento da data da ultima carga
    $http.get('/siigf/ws/imr/dataUltimaCarga').
    then(function(response) {
         $scope.dataUltimaCarga = response.data;
    });

Html

{{app.name}}{{app.version.id}}

{{app.version.name}}

I also imported the infoBuild.js file into index.html

The project is in angular JS

Thank you!
