Sequelize - return object from 2nd level chain after last callback execution is complete - callback

Question

in the addBussiness method, I create a business object and then use the result to create a UserBusiness object in the database using sequelize.
I want to return the Business object created after the UserBusiness object is done creating.
As it stands now I think due to the asynchronous nature of Javascript, the business object is returned before the UserBusiness object is done creating.
Is there a way to return the object from the 1st callback in the 2nd callback?
addBusiness(_,args) {
// this is needed to put it correctly in the geometry point format that the database expects
var point = { type: 'Point', coordinates: [args.input.location.longitude,args.input.location.latitude] };
args.input.location = point;
return Business.create(args.input, {
include: [{
association: Hours,
as: 'hours'
}]
}).then(business => {
UserBusiness.create({userId: args.input.userId, businessId: business.businessId})
return business; // this might get returned before UserBusiness.create is done executing
})
},
here is my mapping defined in sequelized:
UserAccountModel.belongsToMany(BusinessModel, { through: UserBusinessModel, foreignKey: 'user_id'});
BusinessModel.belongsToMany(UserAccountModel, { through: UserBusinessModel , foreignKey: 'business_id'});

You can return UserBusiness object after creation and then return UserBusiness.bussiness or save business object in a variable and return the variable after UserBusiness object is created.
addBusiness(_,args) {
var point = { type: 'Point', coordinates: [args.input.location.longitude,args.input.location.latitude] };
args.input.location = point;
return Business.create(args.input, {
include: [{
association: Hours,
as: 'hours'
}]
}).then(business => {
return UserBusiness.create({userId: args.input.userId, businessId: business.businessId})
}).then(UserBusiness => {
return UserBusiness.business;
})
}
OR
addBusiness(_,args) {
var _business;
var point = { type: 'Point', coordinates: [args.input.location.longitude,args.input.location.latitude] };
args.input.location = point;
return Business.create(args.input, {
include: [{
association: Hours,
as: 'hours'
}]
}).then(business => {
_business = business;
return UserBusiness.create({userId: args.input.userId, businessId: business.businessId})
})
.then(() => {
return _business;
})
}
