AngularJS how to force an input to be re-rendered on blur

Question

I have some custom validation code, which includes a $formatter. (I store currency in pence for correctness, but display in pounds.pence.)

If the user types \'10\'

Answer 1

Your controller's $modelValue is being updated properly, however, but since the blur event is happening outside of angular, it seems your $viewValue is not. How about this?

 elm.bind('blur', function() {
       ctrl.$viewValue = (ctrl.$modelValue / 100).toFixed(2);
       ctrl.$render();
 });
