title: computed field knockout same value
body: <p>In Knockout I'm trying to have an entry field be auto-formatted, very similar to the example on this page under Writable Computed Observables:</p>

  <p>The problem I have is that if you enter values that get converted to the same thing (e.g. 1.00 and 1.0) then Knockout doesn't see that the value has changed and won't update the formatting (you can use the example on his page and see). I've created a hackjob solution where we change the field to something different and then change it back to trigger the update in Knockout, but I was wondering if someone had a more proper fix.</p>
  
  <p>Thanks.</p>
