Using a custom Ember.View works for me, but I think there is a better solution...

See working example is this fiddle http://jsfiddle.net/pangratz/hcxrJ/

Handlebars:

{{#view Food.SelectView contentBinding="Food.foodController"
    valueBinding="Food.appsController.selectedValue"}}
    
        {{#each content}}
            {{title}}
        {{/each}}
    
{{/view}}

app.js:

Food = Ember.Application.create();

Food.SelectView = Ember.View.extend({
    value: null,

    valueChanged: function(){
        this.$('select').val( this.get('value') );
    }.observes('value'),

    didInsertElement: function(){
        var self = this;
        this.$('select').change(function(){
            var val = $('select option:selected').val();
            self.set('value', val);
        });
    }
});

Food.appsController = Ember.Object.create({
  selectedValue: ""
});

Food.Todo = Ember.Object.extend({
  title: null,
  value: null
});

Food.foodController = Ember.ArrayProxy.create({
  content: []
});

Food.foodController.pushObject(Food.Todo.create({title:"a", value:"1"}));
Food.foodController.pushObject(Food.Todo.create({title:"b", value:"2"}));
Food.foodController.pushObject(Food.Todo.create({title:"c", value:"3"}));
