ARIA attributes in ember core form components

I'd like to use ARIA attributes in Ember core form components, such input and textarea fields.

I noticed that using an aria attribute within the component in my template, it doesn't work at all

{{input aria-label="Your name"}}
{{textarea aria-label="Your address"}}

So I decided to reopen the core components in an initializer to add this attribute to the components

export default {
    name: 'reopenTextAreaComponent',

    initialize: function () {
        Ember.TextArea.reopen({
            attributeBindings: ['aria-label']
        });
    }
};

Since I did that, the performance of my application is pretty bad. The integration tests take much more time than before.

I tried not to use their components and simply a HTML tag:

<textarea {{bind-attr aria-label="Your address"}}>{{value}}</textarea>

But this doesn't compile with handlebars! It returns an error because of the {{value}} within the textarea tag.

What is the solution to avoid reopening? Should I create my own component?

Thanks
