Call to undefined method DataTables\Controller\Component\DataTablesComponent::callback()

Hi,

I am loading $columns from the controllers and pass them to the view with set.

After setting the render attribute in the columns array like in your documentation CakePHP was giving the following error:

Call to undefined method DataTables\Controller\Component\DataTablesComponent::callback()

I found out callback was only in DataTablesHelper not in the Component.
I copied this function to DataTablesComponent:

public function callback(string $name, array $args = []) : CallbackFunction
{
        return new CallbackFunction($name, $args);
}

And added use to the top of DataTablesComponent

use DataTables\Lib\CallbackFunction;

Now it's working fine, but not sure it was meant to work like this?
Or did you add it to Helper with the purpose of loading $columns in the view?

The columns are shared between controller and view, but the callbacks are a pure view matter.

I suggest you use ColumnDefinitions interface and add the callback in the view. Like $columns['name']['callback'] = ….

You are right, thats working fine. Thanks!
