Angular - Choose from list and set to button

I have this directive :

app.directive('sampleDirective' , function () {
    return {
        controller: function ($scope) {
            $scope.numbers = [
                    {number : '1 '},
                    {number : '2 '},
                    {number : '3'},
                    {number : '4'},
                ];
        }
    }
});

I call this number in list like this:

          <sample-directive>
          <button type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" class="btn btn-dropdown dropdown-toggle">choose number<i class="icon icon-arrow-down"></i></button>
          <ul class="dropdown-menu list-unstyled text-right">
              <ul>
                <li ng-repeat="x in numbers">
                  <a href = "#"> {{ x.number }} </a>
                </li>
              </ul>
          </ul>
          </sample-directive>

At this moment , list can show numbers but I want to change choose number to selected value..(for example if I choose 1 I want to set it as value of button) How to do that?

May be this can work

 <a href = "#" ng-click="setNumber(x.number)"> {{ x.number }} </a>

 $scope.setNumber = function(num){
 $scope.btnValue = num

 }

<button type="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false" class="btn btn-dropdown dropdown-toggle">choose number<i class="icon icon-arrow-down" ng-value="btnValue"></i></button>

In your controller:

$scope.setSelectedNumber = function(n) {
    $scope.selectedNumber = n;
}

In your link:

<a href="" ng-click="setSelectedNumber(x.number)"> {{ x.number }} </a>

In your button:

{{ selectedNumber ? selectedNumber : 'choose number' }}

or even simpler:

{{ selectedNumber || 'choose number' }}
