setViewValue in directive on input not updating actual visible input value
You need to call ngModel.$render() to have the viewvalue change reflected in the input. There is no watch created on $viewValue so that changes are automatically reflected.
function setAnotherValue() { ngModel.$setViewValue("I'm a new value of the model. I've been set using the setViewValue method"); ngModel.$render(); }Default implementation of $render does this:-
element.val(ctrl.$isEmpty(ctrl.$viewValue) ? '' : ctrl.$viewValue);However you can override and customize your implementation for $render as well..
try scope.$apply() to invoke change on model since you're liking changing model outside of scope where ngModel was inited
