Sequelize hasMany through another table

Okay so i have the following three models

Module:

    var Module = sequelize.define('module', {
        id: DataTypes.INTEGER,
        name: DataTypes.STRING,
        description: DataTypes.STRING,
        category_id: DataTypes.STRING,
        module_type_id: DataTypes.STRING,
        gives_score: DataTypes.INTEGER,
        duration: DataTypes.STRING,
        price: DataTypes.STRING

    }, {
        freezeTableName: true}
)

Competence:

Competence = sequelize.define('competence', {
        id: DataTypes.INTEGER,
        name: DataTypes.STRING,
        organization_id: DataTypes.INTEGER,
        competence_type_id: DataTypes.INTEGER
    },{freezeTableName:true})

Module_has_competence:

        Module_has_competence = sequelize.define('module_has_competence', {
    id: DataTypes.INTEGER,
    module_id: DataTypes.INTEGER,
    competence_id: DataTypes.INTEGER,
    score: DataTypes.STRING
},{
    freezeTableName: true}
})

As you can see the relation between the tables are an n:m

So now i want to find all the Competence that a Module has:

So i created the following relationship:

Module.hasMany(Competence, {through: Module_has_competence, foreignKey: 'module_id'});

However when i try to run:

  retrieveById: function (quote_id, onSuccess, onError) {
                Module.find({include: [{ all: true }],where: {id: quote_id}})
                    .success(onSuccess).error(onError);
            }

it returns nothing. But if i delete the relationship it returns only the Module

Can anyone tell me what i am doing wrong?

When i debug

When i debug it does not log any sql sadly it seems it is just ignoring the sql call ?
