I'm using ember-forms in newly created Ember-CLI project, but the layout for horizontal forms seems to be broken.
Template:
{{#em-form model=model form_layout="horizontal"}}
{{em-input label="Name" property="name"}}
{{/em-form}}
Output looks like this:

It seems that label element doesn't have col-sm-2 class.
Also additional submit button is automatically created that is not described in ember-forms classes. How to disable that button?
