mongoose remove from nested documents

I have the following two schemas and models: ``` var Customer = new Schema({ name: String, jobs: [{ type: Schema.Types.ObjectId, ref: 'Job' }] }); var Job = new Schema({ title: String, customer: { type: Schema.Types.ObjectId, ref: 'Customer' } }); var CustomerModel = mongoose.model('Customer', Customer); var JobModel = mongoose.model('Job', Job); ``` job documents have a reference to the customer document via _id, and the customer document also contains an array of all the jobs _id's. When I delete a job I need to delete the corresponding _id from the Customer.jobs array. Here is the route I have - the job gets deleted but I cannot remove it's id from the array ``` app.delete('/api/jobs/:jobId', function(req, res){ return JobModel.findById(req.params.jobId, function(err, job){ return job.remove(function(err){ if(!err){ CustomerModel.update({_id: job.customer._id}, {$pull : {'customer.jobs' : job.customer._id}}, function(err, numberAffected){ console.log(numberAffected); if(!err){ return console.log('removed job id'); } else { return console.log(err); } }); console.log('Job removed'); return res.send(''); } else{ console.log(err); } }); }); }); ``` numberAffected is always 0 and 'removed job id' always get fired
