Binding emberjs

Binding emberjs

I'm having issues with binding to emberjs. I bound the ember field to a variable inside the controller. When I write to the text box, the associated variable is updated correctly.

Now I want to change the variable (and the text in the text box) through JS. Nothing happens when I do this.

App = Ember.Application.create({});

App.FormInfo = Em.TextField.extend({
    insertNewline: function(){
        App.AController.clear();
    }
});

App.AController = Em.ArrayController.create({
    content: [],
    name: '',
    clear: function(){ //I want this function to clear the text field and set name to an empty string
        this.name = '';
        console.log(this.name);//expected empty string; actual user input
    }
});
