Ember testing fillIn helper not working

Hey I'm trying to write a test that fills an input and then checks the validity of a button.

test("Recipe add form", function(assert) {
    assert.expect(3);
    visit('recipe/add').then(function() {
        assert.equal(find('.formIsDisabled').length, 1, "Form button is disabled");

        fillIn('input.nameInput', "My new recipe");

        assert.equal(find('.formIsDisabled').length, 0, "Form button is enabled");
        assert.equal(find('input.nameInput').text(), "My new recipe"); 
    });
});

But for some reason the "fillIn" helper does not work.

The template's name input

 {{input type="text" value=recipe.name class="form-control nameInput"}}

The outcome..

Expected: 0 Result: 1

Expected: "My new recipe" Result: ""

When i cancelled App.destroy() i could see that the input was actually filled but the code doesnt seem to accept that..
