Inject $uibModalInstance to a controllar not initiated by a $uibModal

I have these two views:

1) foo.html

  <p>Hello {{name}}</p>

2) foo-as-modal.html

<div class="modal-header">
    <h3 class="modal-title">I'm a modal</h3>
</div>
<div class="modal-body">
    <ng-include src="'foo.html'"></ng-include>
</div>
<div class="modal-footer">
    <button class="btn btn-default" ng-click="cancel()">Close</button>
</div>

The controller for foo.html is fooController:

angular.module('myApp').controller('fooController', ['$scope','$uibModalInstance', function($scope,$uibModalInstance) {

     $scope.name = "John"

     $scope.cancel = function () {
        $uibModalInstance.dismiss('cancel');
     };
}]);

I need to inject $uibModalInstance to fooController for the .dismiss to work

That works great when I invoke foo-as-modal.html as a modal, ie:

    var modalInstance = $uibModal.open({
        templateUrl: 'foo-as-modal.html',
        controller: 'fooController',
        scope: $scope.$new(),
        size: 'lg'
    });

But it throws error when I invoke foo.html as a normal view (via $routeProvider and ng-view directive), ie:

    .when('/foo', {
        templateUrl: 'foo.html',
        controller: 'fooController'
    })

Error is:

 Error: [$injector:unpr] Unknown provider: $uibModalInstanceProvider <- $uibModalInstance <- fooController

And the view doesn't display "John" (because of the error)

How can I solve this? I really NEED to reuse foo.html and fooController as a modal and non-modal, because they have lots of stuff (I've simplified here)

EDIT: Here is a plunkr:

Well I solved this way:

1. Removed the injection $uibModalInstance from fooController

2. When invoking the modal, I pass the modalInstance as a variable to the modal's scope:

   var modalScope = $scope.$new();
   
   var modalInstance = $uibModal.open({
       templateUrl: 'foo-as-modal.html',
       controller: 'fooController',
       scope: modalScope
   });
   
   modalScope.modalInstance = modalInstance;
   

3. Dismiss the modal with the scope variable:

   $scope.modalInstance.dismiss('cancel');  // instead of $uibModalInstance.dismiss(..)
