self.bothrate etc are not knockout observables at the time they are accessed in your code. You have them defined in your html and they are just regular strings.

So try this instead:

self.addTierFields = function (tier) {
       self.Tiers.push(new Tier({
        bothrate: self.bothrate,
        compoundratee: self.compoundratee,
        simplerate: self.simplerate,
        rate: self.rate 
       }));
        self.show(true);
    };

In the snippet bellow 

 self.Tiers.push(new Tier({
            bothrate: self.bothrate(),
            compoundratee: self.compoundratee(),
            simplerate: self.simplerate(),
            rate: self.rate()
  }));

There is no bothrate in LoanViewModel, I have also changed a number of things, understand the concepts of scope, meaning of $root,$parent,$data.

here is the new fiddle
