Hi.

I'm trying to access the Id property of an object within the save method of a model, but, it returns me an undefined error.

Example:

var campaign = Campaign.create({

    deviceId: 1,

    campaignTypeId: 1,

    campaignStatusId: 1,

    campaignPriorityId: 2,

    description: 'Testing stuff',

    sendBySatellite: false,

    file: null,

    data: '386690,386691,386692,386693,386694,386695,386696,386697,386698,386699,386700',

});

campaign.save(function(err, data) {

    

    // this returns undefined

    console.log(data.id)

});

Could someone help me, please? 

Thanks!
