Have can I force the client browser to download the latest copy of the MyProperty.js?

The .js is not in a bundle and I cannot add a querystring to the reference as the file is never referenced in a classic way.

I've built a Custom Dojo widget and placed it at \ClientResources\Scripts\Editors\MyProperty.js together with a html-template and a CSS.

In my module.config I have:

And I've added a EditorDescriptor:

    [EditorDescriptorRegistration(TargetType = typeof(IEnumerable))]
    public class ListboxDescriptor : EditorDescriptor
    {
        public ListboxDescriptor()
        {
            ClientEditingClass = "alloy/editors/MyProperty";
        }
    }
