title: How to remove the validation rules [extenders] from observable in Knockout Validation
body: <p><a href="https://stackoverflow.com/questions/17120416/how-to-remove-extender-from-knocout-observable">How to remove extender from an existing observable?</a></p>
  
  <p>I tried the above link &amp; can make the observable NOT validatable. But if the check the observable with <strong>ko.validation.utils.isValidatable()</strong> function, it gives me TRUE [it says observable is validatable even after making that as NOT validatable].</p>
  
  <p>Because making <strong>validatable:true</strong> leaves the isValid, isModified, isValidating observables &amp; error variable on the observable property.</p>
  
  <p>Please help me to remove the validation <strong>completely</strong> form the observable property.</p>
