Alloy & Migrations - Create new table with migrations

Whats the procedure to create a new table on a existing app with an already installed db? I'm doing like this:

This is the new table that needs to be created:

exports.definition = {
    config : {
        "columns" : {
            "name" : "string",
            "id" : "int"
        },
        adapter : {
            type : "sql",
            db_file : "/db.sqlite",
            collection_name : "books",
            idAttribute : "id"
        }
    }
};

Migration:

20131112000000_books.js

migration.up = function(migrator) {
    migrator.db.execute("CREATE TABLE IF NOT EXISTS books (name TEXT NOT NULL, id INTEGER NOT NULL );");
};
 
migration.down = function(migrator) {
    migrator.db.execute("DROP TABLE IF EXISTS books;");
};

In the app I do:

var books = Alloy.createCollection('books');

And I get:

12-11 19:04:30.728: E/TiExceptionHandler(13828): (main) [366,366] ----- Titanium Javascript Runtime Error -----

12-11 19:04:30.733: E/V8Exception(13828): Exception occurred at alloy/sync/sql.js:11: Uncaught TypeError: Cannot call method 'isValidRow' of null

Because Alloy is executing "installDatabase" in the sql adapter with the parameter "config.adapter.collection_name" equal to "books", so it tries to check the "pragma table_info" of a table that doesnt exists yet, the migration is not executed before
