ES6 angular-meteor ng-table getData function not called

Question

I'm trying to refactor my code to ES6. I'm using angular-meteor and ng-table. Before refactoring, the data is shown on the table. However, after refactoring to ES6 syntax, the data doesn't show anymore. This is a snippet of the refactored code:

class MyController {
    constructor($scope, $reactive, NgTableParams, MyService) {
        'ngInject';

        $reactive(this).attach($scope);

        this.subscribe('myCollection');

        this.myService = MyService;

        this.helpers({
            items() {
                return this.myService.getItems();
            },
            itemTableParams() {
                const data = this.getReactively('items');

                return new NgTableParams({
                    page: 1,
                    count: 10
                }, {
                    total: data.length,
                    getData: (params) => {
                        // not called
                    }
                });
            }
        });
    }
}

class MyService {
    getItems() {
        return MyCollection.find({}, {
            sort: {
                dateCreated: -1
            }
        });
    }
}

export default angular.module('MyModule', [angularMeteor, ngTable, MyService])
    .component('MyComponent', {
        myTemplate,
        controllerAs: 'ctrl',
        controller: MyController
    })
    .service('MyService', MyService);

The const data is getting populated but getData isn't getting called. The table in the template is using ctrl.itemTableParams as the value for ng-table attribute and its ng-repeat is item in $data.

Does anyone have an idea as to why the getData function isn't called? Help would be greatly appreciated. Thanks!

P.S. When I try to set NgTableParams to a const tableParams, and then call the reload() function, getData is triggered. But the thing is, it's not rendering the data on the table. I set the table as:

itemTableParams() {
    const data = this.getReactively('items');
    const tableParams = new NgTableParams({
        page: 1,
        count: 10
    }, {
        total: data.length,
        getData: (params) => {

        }
    });

    tableParams.reload(); // triggers the getData function
    return tableParams;
}


<table ng-table="ctrl.itemTableParams">
    <tr ng-repeat="item in $data track by $index">
        <td>{{item.id}}</td>
        <td>{{item.name}}</td>
        <td>{{item.dateCreated}}</td>
    </tr>
</table>

When I log the data in getData, it has items in it. But, like I said, it's not rendering in the table.

Apparently, you just need to return the data in getData. The old docs were using $defer.resolve and was not returning the resolved data. The current version (1.0.0) isn't using it anymore.

this.helpers({
  items() {
    return this.myService.getItems();
  },
  itemTableParams() {
    const data = this.getReactively('items');

    return new NgTableParams({
      page: 1,
      count: 10
    }, {
      total: data.length,
      getData: (params) => {
        const filteredData = filterData(data); // do something

        return filteredData;
      }
    });
  }
});
