create record using ember loopback and mongodb

I am having a problem in my code .. the thing is i want to store some data from an ember js applications using loopback api and mongodb

actually i have two problems

first one is that the data i want to store into the database is stored in a "data" key and i can't access it "no idea why"

Here is my template

      <div class="form-group">
    <div class="input-group">
      <span class="input-group-addon">Per Minute </span>
    </div>
  </div>
  <br />
  <div class="form-group">
    <div class="input-group">
      <span class="input-group-addon">˚C</span>
    </div>
  </div>
  <br />
<div class="form-group">
  <div class="input-group">
    <span class="input-group-addon">to</span>
  </div>
</div>
<br />
<div class="form-group">
  <div class="input-group">
    <span class="input-group-addon">Per Minute</span>
  </div>
</div>
<br />
</div>
<button  class="btn btn-primary pull-right"> Save </button>

Here is my controller :

    addOrder(services, doctor, patient, visit){
  patient.then((patient)=>{
      doctor.then((doctor)=>{
    var order = this.store.createRecord('order',{
      doctor:doctor,
      patient:patient,
      visit:visit
    })
    visit.get('orders').pushObject(order);
    patient.get('orders').pushObject(order);
    order.get('services').pushObjects(services);
    order.save().then(()=>{
      patient.save();
      doctor.save();
      })
    })
  })
}

My order.json :

{
  "name": "order",
  "plural": "orders",
  "base": "PersistedModel",
  "idInjection": true,
  "options": {
    "validateUpsert": true
