Autoform update-pushArray

I am trying to create a modal to only update-pushArray on a certain scope.
I am using autoform

My JS on the client

Template.prospectos.events({
    'click .updateP' : function(){
      var prospectosId = this._id;
      Session.set('selectedClient',prospectosId);
      var selectedClient = Session.get('selectedClient')
      $('#updateProspectos').modal('show');
      console.log(selectedClient)
    }
  });

  Template.updateProspectos.helpers({
    prospectosShow: function(){
      var selectedClient = Session.get('selectedClient');
      return Clientes.findOne(selectedClient);
    }
  })

My html

  {{> quickForm id="updatePushForm"
      type="update-pushArray"
      collection=Collections.PeopleWithContacts
      doc=selectedClient
      scope="llamadas"}}

Part of my schema

llamadas:{
    type:Array,
    optional:true,
  },
  'llamadas.$': {
    type: Object,
    optional:true
  },
  'llamadas.$.fecha': {
   type: String,
   label:"Fecha",
   optional:true,
   autoform:{
     afFieldInput:{
       type:"date"
     }
   }
 },
'llamadas.$.contacto':{
  type:String,
  optional:true,
  label:"Contacto"
},
'llamadas.$.observacion':{
  type:String,
  optional:true,
  label:"Observacion"
}

What am I not getting?
