I would like to be able to pass additional arguments to my edit-callback. Normally with directives this is done by passing a function expression instead of a function reference. e.g. `edit-callback="onEdit(userId, text)" On the directive side it can be handled with something like:

var fn = $parse($attrs.editCallback);
fn($scope, { text: text, element: element });

Are you open to a change like that?
