select dropdown with ember - ember.js

Question

I'm trying to produce a select input and pass the selected object to the change event on the view. The ember contact example uses a <ul> but with a select the view needs to be outside the each otherwise the change even isn't fired.
Here is the view js:
App.SelectView = Ember.View.extend({
change: function(e) {
//event for select
var content = this.get('content');
console.log(content);
App.selectedWidgetController.set('content', [content]);
},
click: function(e) {
//event for ul
var content = this.get('content');
console.log(content);
App.selectedWidgetController.set('content', [content]);
}
});
The ul from the example works:
<ul>
{{#each App.widgetController.content}}
{{#view App.SelectView contentBinding="this"}}
<li>{{content.name}}</li>
{{/view}}
{{/each}}
</ul>
But if I replace html directly, the change event isn't fired (which makes sense)
<select>
{{#each App.widgetController.content}}
{{#view App.SelectView contentBinding="this"}}
<option>{{content.name}}</option>
{{/view}}
{{/each}}
</select>
So I guess the select has to be wrapped in the view.. in which case how do I pass the relevant object?... This code results in the entire array being passed:
{{#view App.select_view contentBinding="App.widgetController.content"}}
<select>
{{#each App.widgetController.content}}
<option>{{name}}</option>
{{/each}}
</select>
{{/view}}

Ember now has a built-in Select view.
Here's a usage example:
var App = Ember.Application.create();
App.Person = Ember.Object.extend({
id: null,
firstName: null,
lastName: null,
fullName: function() {
return this.get('firstName') + " " + this.get('lastName');
}.property('firstName', 'lastName').cacheable()
});
App.selectedPersonController = Ember.Object.create({
person: null
});
App.peopleController = Ember.ArrayController.create({
content: [
App.Person.create({id: 1, firstName: 'Yehuda', lastName: 'Katz'}),
App.Person.create({id: 2, firstName: 'Tom', lastName: 'Dale'}),
App.Person.create({id: 3, firstName: 'Peter', lastName: 'Wagenet'}),
App.Person.create({id: 4, firstName: 'Erik', lastName: 'Bryn'})
]
});
Your template would look like:
{{view Ember.Select
contentBinding="App.peopleController"
selectionBinding="App.selectedPersonController.person"
optionLabelPath="content.fullName"
optionValuePath="content.id"}}

check out the answers to a similar question: How to bind value form input select to attribute in controller
In the examples a CollectionView is used with an tagName=select. You may find this helpful in getting it work.
EDIT: Since I was looking to implement a select myself, here is the solution I came up with:
views/form.js.hjs:
{{#view contentBinding="App.typeController" valueBinding="type" tagName="select"}}
{{#each content}}
<option {{bindAttr value="title"}}>{{title}}</option>
{{/each}}
{{/view}}
{{#view Ember.Button target="parentView" action="submitEntry"}}Save{{/view}}
The select is part of a form. I do check for the submit event and in there read the value:
app.js.coffee
# provides the select, add value: 'my_id' if you need differentiation
# between display name (title) and value
app.typeController = Ember.ArrayProxy.create
content: [{title:'Energy'}, {title:'Gas'}, {title:'Water'}]
# simplified version, but should prove the point
app.form_view = Ember.View.create
templateName: 'views_form'
type: null
submitEntry: () ->
console.log this.$().find(":selected").val()
Hope this helps.

This isn't an Answer, just a fix on the broken jsfiddle link.. Apparently jsfiddle has no love for ember :/ But JsBin does! http://jsbin.com/kuguf/1/edit
