How to dynamically change view in angularjs using ui-router - node.js

Question

I have a named view called myView in which I have two div elements that I want to show conditionally using ng-show based on whether the value of $scope.states['currentState'] is 'A' or 'B'. The value of $scope.states['currentState'] is changed when an anchor tag is clicked which calls the doStuff function on the myController controller.
The issue I am having is when the anchor tag is clicked and the doStuff function is clicked, it shows on the console that the value of $scope.states['currentState'] has been modified, but its not updating the myView named view accordingly.
Following is the code for app.js, myView.html and index.html files. The index.html file is being used as a <div ui-view></div> in an index.ejs file that I am rendering using Express with Node.js.
app.js
var app = angular.module("app", ['ui.router']).
config(['$stateProvider', '$urlRouterProvider', '$locationProvider', function($stateProvider, $urlRouterProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$urlRouterProvider.otherwise('/');
$stateProvider
.state('home', {
url: '/',
views: {
'': { templateUrl: 'partials/index.html' },
'myView#home': {
templateUrl: 'partials/myView.html',
controller: 'myController'
},
'myOtherView#home': {
templateUrl: 'partials/myOtherView.html',
controller: 'myController'
}
}
});
}])
app.controller("myController", ['$scope', function($scope){
var states = ['A', 'B'];
$scope.states = states;
$scope.states['currentState'] = states['currentState'] || 'A';
$scope.doStuff = function(toState) {
//doing stuff
$scope.states['currentState'] = toState;
console.log($scope.states['currentState']);
};
} ]);
index.html
<div class="main">
<div class="container">
<div class="row margin-bottom-40">
<div class="col-md-12 col-sm-12">
<div class="content-page">
<div class="row">
<div ui-view="myView"></div>
<div ui-view="myOtherView"></div>
</div>
</div>
</div>
</div>
</div>
</div>
myView.html
<div ng-controller='myController'>
<div ng-show="states['currentState'] == 'A'">
//displaying this div if the currentState is A
<a ng-click="doStuff('B')">Do stuff and show B</a>
</div>
<div ng-show="states['currentState'] == 'B'">
//displaying this div if the currentState is B
</div>
</div>
Could somebody help me understand that why am not getting the div with states['currentState'] == 'B' shown, even when I see the value of console.log($scope.states['currentState']) changed from 'A' to 'B' when the doStuff function is called in myController?
Edit:
Here is the demo of the issue I am facing.

Okay So I was mistaken in my comment.
The real issue was that you used {{}} in your ng-show which is not needed as these expect to take angular expressions.Also I would make current state a property of your scope as at the moment you are trying to make it a property of an array inside your scope.
Hope that helps! Below is the modified code for your view:
<div ng-controller='MainCtrl'>
<div ng-show="currentState === 'A'">
<a ng-click="doStuff('B')">Do stuff and show B</a>
</div>
<div ng-show="currentState === 'B'">
<a ng-click="doStuff('A')">Do stuff and show A</a>
</div>
</div>
