How to use one controller inside another one - angularjs

Question

I would like to use one controller inside another one. I have found that I could use angular service $controller.
This is what I have tried:
.controller(
'UnplannedTasksController',
[
'$location',
'$uibModal',
'$controller',
'unplannedTasksService',
'messages',
function($location, $uibModal, $controller, unplannedTasksService, messages) {
var ctrl = this;
var modalInstanceCtrl = $controller('ModalInstanceCtrl');
this.openModal = function(unplannedTask) {
var modalInstance = $uibModal.open({
animation: false,
templateUrl: 'unplanned-tasks/unplanned-tasks-modal.html',
controller: modalInstanceCtrl,
controllerAs: 'mdCtrl',
size: 'lm',
resolve: {
object: function() {
return unplannedTask;
},
title: function() {
return messages.unplannedTasks.deleteTitle;
},
question: function() {
return messages.unplannedTasks.deleteQuestion + unplannedTask.partner.name;
}
}
});
modalInstance.result.then(function(unplannedTask) {
ctrl.display.getUnplannedTasksBusyPromise = unplannedTasksService.removeUnplannedTask(unplannedTask.id).then(function(data) {
ctrl.searchUnplannedTasks();
});
});
};
}])
This ModalInstanceCtrl is in another file and look like this:
.controller('ModalInstanceCtrl', function($modalInstance, object, title, question) {
var ctrl = this;
this.object = object;
this.title = title;
this.question = question;
this.ok = function() {
$modalInstance.close(ctrl.object);
};
this.cancel = function() {
$modalInstance.dismiss('cancel');
};
})
But I am getting an error:
"Error: [$injector:unpr] Unknown provider: $modalInstanceProvider <- $modalInstance <- ModalInstanceCtrl ..."
Could you please advise. Thank you.
[EDIT]
Anyone? Please ...
Best regards,

According to the Angular-UI documentation, you do not need to use $controller. You just have to tell the controller name the the $uibModal service, as a simple string.
In your case:
var modalInstance = $uibModal.open({
controller: 'modalInstanceCtrl'
// + more params
});
