Toolbar buttons disabled

I want to use an inline editor when an element was double clicked.

I use this code:

    var $elm = $(node);

    var editor = CKEDITOR.inline(node);

    $elm.dblclick(function() {
        $elm.attr("contentEditable",true);
        $elm.focus();
    });

    editor.on("blur",function(e) {
        $elm.attr("contentEditable",false);
    });

This seems to work (with some strangeness in IE versions), but all buttons in the toolbar are disabled. How can I prevent this or enabled them again?
