angular ui router - having to click twice for view to update as expected (with demo)

I am a novice with Angular and just getting to grips with the AngularUI Router framework. I have one html page which contains a list of questions (each question needs its own url) and a results page.

I have created a quick stripped down plunker (with all files) to demo the issue:

For SO ref:

app.js

angular.module('foo', ['ui.router'])

.config(function($stateProvider, $urlRouterProvider) {

    $urlRouterProvider.otherwise('/q1');

    $stateProvider

    .state('question', {
        url: '/:questionID',
        templateUrl: 'questions.html',
        controller: 'questionsCtrl'
    })

    .state('results', {
        url: '/results',
        templateUrl: 'results.html'
    })

})

.controller('questionsCtrl', function($scope, $stateParams) {

    $scope.questionID = $stateParams.questionID;
    $scope.scotches = [
        {
            name: 'Macallan 12',
            price: 50
        },
        {
            name: 'Chivas Regal Royal Salute',
            price: 10000
        }
    ];

});

Basically for some unknown reason (to me) I have to click the 'results' link twice for it to appear in my eyes should appear on the first click.

Does anyone know why this is happening?

What we should do is to reverse the state defintion:

.state('results', {
    url: '/results',
    templateUrl: 'results.html'
})
.state('question', {
    url: '/:questionID',
    templateUrl: 'questions.html',
    controller: 'questionsCtrl'
})

The reason why?

because the question state definition is covering also the /results as a param /:questionID

But in general, this is still confusing, so I would distinguish the url more, e.g. with /question keyword

.state('results', {
    url: '/results',
})
.state('question', {
    url: '/question/:questionID',
    ...
})
