Remove bottom branding from tiny mce in django templates

I am using tiny mce HtmlField() in my django models. Every thing works file but the bottom branding in the field annoys me. Is there any way to remove branding in django template.

This supposed to work.

tinymce.init({
    selector: '#tinymce-div',

    // Disable branding message, remove "Powered by TinyMCE"
    branding: false
});

note: If you are developing a product using there open source license you should consider keeping the text. That's a courtesy we all should follow.
