inline ckeditor is disbaled, how to enable?

Hi, I've initialized ckeditor by addint contenteditable attribute to div, but most of the panel buttons are diabled, like so:

This is my HTML:

                <div contenteditable="true">

                    <p>Test</p>

                </div>

Console does not show any errors. What could be wrong? Im using symfony2 and trsteel bundle for integration. Maybe I've missed something in config. config.js is at it's default values.

                <div contenteditable="true">                     <p>Test</p>                 </div>
