If you have a scope with a function like so:

@Scopes({ something: function (id) { return { where: {id: id} } } }) 

It doesn't get added properly to the Sequelize model. I was ready to open a PR to fix this, but I think it's beyond my knowledge of this module. The problem is in resolveScope in the lib/services/model file, it should check if the options is a function and if so, just add the scope. I'm not sure if there is something else that needs to be done to the function.
