Ember 2.2 select relationship/nested

Can someone help with example of related/nested select on ember 2.2? I create component app/components/link-pin-device.js

export default Ember.Component.extend({
  selectedPin:  null,
  actions: {
    selectPin(pin, wdevice) {
      console.log(pin);
      console.log(wdevice);
    }
  }
});

app/templates/components/link-pin-device.hbs

<select value="target.value" onchange={{action "selectPin" "target.value"}}>>
    <option value="">Select...</option>
  {{#each dcPinConfigs as |pinconf|}}
      <option value={{pinconf.id}} selected={{eq selectedPinId pinconf.id}}>{{pinconf.id}}</option>
  {{/each}}
</select>
{{yield}}

app/routes/web-device-module.js

export default Ember.Route.extend({
  model() {
    var self = this;
    return Ember.RSVP.hash({
      webDeviceModules: self.store.findAll('webdevicemodule'),
      dcPinConfigs: self.store.findAll('dcPinConfig').then(function(d){
        let dPin = self.store.peekRecord('dcPinConfig', 2);
        let wMods = self.store.createRecord('webdevicemodule', {
          dcPinLink: dPin,
          name: "sda"
        });
        comment.save();
        return d;
      })
    });
  },
});

How i can change model webdevicemodule.dcPinLink then change value in select?
