nested ui-router $location binding - angularjs

Question

I have some problem with binding when i use ui-router. I am trying to make the app modular and keep it clean and simple.
I have the following app.js
// main routing - index.html
var app = angular.module('mainApp', ['ui.router']);
app.config(function($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/');
$stateProvider
.state('index', {
url: '/',
templateUrl: 'pages/main.html'
})
.state('cars', {
url: '/cars',
templateUrl: 'pages/Cars_model/main.html'
})
.state('cars.audi', {
url: '/audi',
templateUrl: 'pages/Cars_model/audi.html'
})
.state('cars.ford', {
url: '/ford',
templateUrl: 'pages/Cars_model/ford.html'
})
});
app.controller('indexController', function($scope, $location) {
$scope.isIndexPage = function() {
return $location.path() === '/';
}
});
app.controller('carsCtrl', function($scope, $location) {
if($location.path() === '/cars/audi')
{
$scope.pageHeader = "AUDI";
$scope.curentMenu = "Best Cars";
$scope.title = "Audi Specs";
}
if($location.path() === '/cars/ford')
{
$scope.pageHeader = "FORD";
$scope.curentMenu = "Best Cars";
$scope.title = "Ford Specs";
}
});
and the file where i want to use binding
<div class="container" ng-controller="carsCtrl">
<div class="page-header">
<h1>{{pageHeader}}</h1>
</div>
<!-- The first row -->
<div class="row">
<div class="col-lg-12 col-md-12 col-sd-12">
<ol class="breadcrumb">
<li>Home</li>
<li>{{curentMenu}}</li>
<li class="active">{{pageHeader}}</li>
</ol>
</div>
</div>
</div>
The problem is when i load the page the binding work only once, for the second i have to refresh the page.
I am not sure if i used the corect logic
if($location.path() === '/cars/ford')

Answer 1

I think i found the solution
Using
ui-sref-opts="{reload: true}"
in the menu solve the problem
<a ui-sref="cars.audi" ui-sref-opts="{reload: true}">Audi</a>
