You can't preserve the actual functions. You can use the callback to save some additional data however and use that to work out what should happen on restore:

var json = paper.toJSON(function(el, data) {
    data.isDraggable = true;

    return data;
});

paper.fromJSON(json, function(el, data) {
    if ( data.isDraggable ) {
        el.drag(...);
    }

    return el;
});
