A manual subscription in your view model is a good way to handle something like this. The subscription might look like:
this.VehicleType.subscribe(function(newValue) { if (newValue === "New") { this.Mileage(0); } }, this);Here is a sample using it: http://jsfiddle.net/rniemeyer/h4cKC/
The HTML:
The JS:
var ViewModel = function() { this.VehicleType = ko.observable(); this.Mileage = ko.observable(); this.VehicleType.subscribe(function(newValue) { if (newValue === "New") { this.Mileage(0); } }, this); }; ko.applyBindings(new ViewModel());
