GATT service on RuuviTag

Ok, I understand I can't put the characteristic I want in a random service.
I tried to follow the requirement for the heart rate service but I still have the same problem. It's says Unable to find the service with UUID 0x2A37.

var Ruuvitag = require("Ruuvitag");

Ruuvitag.setEnvOn(true);

NRF.setServices({
  0x180D: {
    0x2902:{
      value: 0,
      read: true,
      write: true,
    },
    0x2A37: {
      notify: true,
      value : [Math.round(Ruuvitag.getEnvData().temp)]­,
    }
  }
}, { advertise: [0x180D] });

setInterval(function () {
  NRF.updateServices({
    0x180D: {
      0x2A37: {
        value : [Math.round(Ruuvitag.getEnvData().temp)]­,
        notify: true
      }
    }
  });
}, 1000);
