Bending Ember Data Records in Input Select

With this data structure:

App.Publisher = DS.Model.extend({
    name: DS.attr('string'),
    books: DS.hasMany('book',  {async: true})
});

App.Book = DS.Model.extend({
    title: DS.attr('string'),
    summary: DS.attr('string'),
    author: DS.belongsTo('author', {async: true}),
    publisher: DS.belongsTo('publisher', {async: true})
};

In the book edit and book new forms, I'd like to display the publishers using a <input type=select>element.

My questions:

1 : how do I bind the ember-data publishers records to the input element.

2: how do I select the current book publisher in the element for edit or a default for a new book

3: how do I bind the selected publisher to the book, when submitting the form

Thanks a lot.
