backbone views - List editor and events of its items editors -

i have simple model:

var listitem = backbone.model.extend({     schema: {         name: 'text',     } }); 

and simple model has list inside:

var configuration = backbone.model.extend({     schema: {         list: {             type:     'list',             itemtype: 'nestedmodel',             model:    listitem         }     } }); 

and form:

var form = new backbone.form({ model: configuration }).render(); 

i need listen events on listitem's "name" editor.

when use this:

form.on('all', function() { console.log('print something') }); 

i did not "name" editor.

i've tried lot of other events names non of them working in case.

how can listen change events on listitem's "name" editor?
