I'm currently working on a project using Angular 1.1.5. Upgrading Angular is not an option for now.
We would like to implement a rich HTML5 WYSIWYG-editor and dicided to give Froala a try, as it meets our requirements and the docs of angular-froala state that it should work with all versions of Angular >=1.0 .
I have made a POC on Plunker that uses Angular 1.1.5.

</div>
</body>
</html>
everything seems to work fine except the most important part, the data-binding. Upgrading the Angular version to 1.5.0 fixes the issue in the POC. But as mentioned that is not an option in my case.
Is this a bug? Is the documentation of froala-angular outdated? Is there some kind of workaround besides upgrading Angular? Or am I simply missing something here?
There seems to be an issue with this version of Angular when trying to use ngModel in a directive.
https://github.com/angular/angular.js/issues/1924
When ngModel directive is used on an element that represents a component (implemented via a directive with isolate scope), ngModel is locked into this isolate scope and in order to get out and make ngModel useful the ngModel expression has to be prefixed with $parent.
As suggested in this thread I tried using the $parent prefix and could notice one way data-binding finding place.
<textarea id="froala-sample-2" froala ng-model="$parent.sample2Text"></textarea>
To get my model to be updated, I had to call $apply() in the froala-directive which forces a $digest().
ctrl.updateModelView = function () {
var returnedHtml = element.froalaEditor('html.get');
if (angular.isString(returnedHtml)) {
scope.$apply(function() {
ngModel.$setViewValue(returnedHtml);
})
}
};
I updated my POC on plunker for those who want to see it running.
