Subscribe doesn't work with Knockout Model as function

I think I'm struggling with the basics here. The code:

var VehicleSearchViewModel = function() {

  this.VehicleVariantId = ko.observable(0);

  this.VehicleVariantId.subscribe(function (id) {
      console.log(id);
  });
};

from the function outside of this, I do the following:

VehicleSearchViewModel.VehicleVariantId = 777;

...and console.log doesn't fire. Albeit if I type VehicleSearchViewModel.VehicleVariantId in the console I can see it's been updated with the new value. What's the right way of doing this?

Knockout observables are functions. You need to set them by passing the new value as a parameter.

VehicleSearchViewModel.VehicleVariantId(777);

You really should go through the tutorials, you are going to have a lot of questions that can be answered by them.
