Did anyone ever succesfully extend the MultiAttachmentsField controller?

Question

Hi, 
 I was wondering if anyone succesfully extended the MultiAttachmentsField Controller? I need to make a small change to the format function so the url that is generated is a bit different for some reason as soon as I make a new file custom/modules/Notes/clients/base/fields/multi-attachments/multi-attachments.js and add the following content the field seems to be broken? 
 
 ({
 extendsFrom: 'BaseMultiAttachmentsField',

 format: function (value) {
 return this.super("format",value);
 }
}) 
 even if I add the contructor to it with this.super('initialize',[options]) in it, it doesnt seem to be working. Any idea's on how to extend it correctly?

For those who are also strugling with this. I got it working by adding a controller to custom/modules/Notes/clients/base/fields/multi-attachments. This controller should extend the BaseNotesMultiAttachmentsField instead of the default like to so: 
 
 ({
 /**
 * Override multi-attachments field for notes
 */
 extendsFrom: 'BaseNotesMultiAttachmentsField',


 init: false,

 initialize: function(options){
 // your custom initialize code here 
 }
 
 // your custom code here..
 
})
