backbone.js - Override saveCompat for WordPress Media Uploader -

i new backbone, can't understand doing wrong. need override savecompat (media-models.js line 310, wp 3.9.1). trying same way have overridden media views

wp.media.model.attachment = wp.media.model.attachment.extend({ savecompat: function( data, options ) { code here... } });

but doesn't work me. native wordpress savecompat executed. @ same time same thought working wp.media.view.attachmentcompat example

wp.media.view.attachmentcompat = wp.media.view.attachmentcompat.extend({ save: function( event ) { code here... } });

thanks in advance!

i figured out. right way extend is:

_.extend( wp.media.model.attachment.prototype, { savecompat: function( data, options ) { code here... } });

wordpress backbone.js override media uploader
