Binding value from textfield when pressing button - ember.js

Question

I have the following example (see below) to work with Ember.js, and everything works alright as far as I enter something in the textfield and press enter. But how can I have the same result when I press the button? How can I bind the value of the textfield when clicking the button? Do I have work with a view?
Thanks in advance!
<script type="text/x-handlebars">
{{view App.TextField}}
{{#view Ember.Button target="App.peopleController" action="addPerson"}}
Add Person
{{/view}}
<ul id='todo-list'>
{{#each App.peopleController }}
<li>{{name}}</li>
{{/each}}
</ul>
</script>
<script>
App = Em.Application.create();
App.peopleController = Em.ArrayController.create({
content: [{name: "Tom"}, {name: "Mike"}],
addPerson: function(name) {
this.unshiftObject(App.Person.create({name: name}));
}
});
App.Person = Em.Object.extend({
name: null
});
App.TextField = Em.TextField.extend({
insertNewline: function() {
App.peopleController.addPerson(this.get("value"));
this.set("value", "");
}
});
</script>

This is actually a little tricky to accomplish, but I've reworked your example in a jsFiddle: http://jsfiddle.net/ebryn/vdmrA/
I would advise against hardcoding references to controllers in your view subclasses. You can't reuse those view components elsewhere if you do that.

I think in your code for the Ember Button is just going to call the addPerson function without giving it the name parameter that it expects. You might have to write a separate view for that button in order to get the value of the input field to pass to the addPerson function.
App.MyButton = Em.Button.extend({
click: function(){
var value = App.TextField.get('value')
// etc
}
