Something like
Code:
{
    control: {
        somecomponentref: {
            someevent: {
                fn: function () {

                },
                single: true,
                element: 'element',
                delegate: 'some html element/component?'
                //etc.
            }
        }
    }
}
expect only function or string in "someevent" but not an object,just like standard listener configuration.

Thanks.
