title: How to force an observable to read the value from the DOM Element
body: <p>I have a hidden input and bind the value to an observable property of my model. I'm using another plugin that internally updates the value of that hidden input, however the observable doesn't update it's value.</p>
  
  <p>How can i force the observable to update it's value from the element? </p>
  
  <p>something like valueHasMutated but in the other way.</p>
  
  <p>Thanks</p>
