The npm module gulp-ng-annotate don't annotate my controller function.

myDirective.js

angular.module('dashboard')
  /**
   * This directive creates the Settings Form.
   * @summary Usage: <printer-settings settings=[MultidimensionalArray]></printer-settings>
   */
  .directive('printerSettings', function($filter, $timeout, RecursionHelper) {
    'use strict';

    return {
      scope: {
        settings: '='
      },
      templateUrl: '/some/path.html',
      compile: compile,
      restrict: 'E',
      transclude: true,
      controller: controller
    };

    function compile(element) {
      return RecursionHelper.compile(element);
    }

    function controller($scope) {
      // use $scope
    }
  });
