@Mutation resolver is not called when dispatching action

[fkolar]

Following todo example from this git and trying to make it work with REST I see @mutation is not called

export class TodosState {
  @Mutation(AddTodo)
  addTodo(args) {
    console.log('Mutation:', args);
    const todo = {
      id: args.id,
      description: args.description,
      completed: args.completed,
      __typename: 'Todo',
    };

    return todo;
  }

After I dispatch action. The only thing that is called is @update().
