What is the expected output? What do you see instead?
I expected to save the content after I feel it. But the application doesn't 
find my text and send me a : cannot be empty

Please provide any additional information below.
I've added this to admin.py
        js = (
            '/static/grappelli/tinymce/jscripts/tiny_mce/tiny_mce.js',
            '/static/js/textarea.js',
)
and my textarea.js is :
    mode: 'exact',
    elements : "id_content_fr,id_content_en",
    theme: 'advanced',
    skin: 'default',

    // General
    accessibility_warnings: false,
    browsers: 'gecko,msie,safari,opera',
    dialog_type: 'window',
    editor_deselector: 'mceNoEditor',
    keep_styles: false,
    language: 'en',
    object_resizing: false,
    plugins: 'advimage,advlink,fullscreen,paste,media,searchreplace,grappelli,template',
    // directionality : "rtl",

... and other stuffs
