angular - update directive template on click

Question

I am trying to build a page using Angular.

I have two templates, say

<script type='text/ng-template' id='a.html'>
    /*some html using {{data}} */
    <div><button>A</button></div>
</script>

and

<script type='text/ng-template' id='b.html'>
    /*some html using {{data}} */
    <div><button>B</button></div>
</script>

I would like to create a directive that changes its template from a to b and vice versa when the button inside the template gets clicked. I tried several options, looking at other answers to similar questions, but without any luck. Can you help me to find the easiest way to do this?

ng-include is a nifty directive that accepts a scope variable as the parameter. this way, you can dynamically load (including other directives from the loaded templates). See the plnkr http://plnkr.co/edit/qxBVDWx6P0F0aNuOymct?p=preview

app.directive('dynamicTemplate', function(){
  return {
    restrict: 'A',
    replace: true,
    template: '<div><div ng-include="var"></div><div>current var: {{ var }}</div></div>',
    controller: function($scope){
      $scope.var = 'template1.html';
      $scope.change = function(where){
        $scope.var = where;
      }
    }
  };
});

but the best way would be just deal with either using $stateProvider or $routeProvider
