Update Angular model after setting input value with jQuery
ngModel listens for "input" event, so to "fix" your code you'd need to trigger that event after setting the value:
$('button').click(function(){ var input = $('input'); input.val('xxx'); input.trigger('input'); // Use for Chrome/Firefox/Edge input.trigger('change'); // Use for Chrome/Firefox/Edge + IE11});
For the explanation of this particular behaviour check out this answer that I gave a while ago: "How does AngularJS internally catch events like 'onclick', 'onchange'?"
But unfortunately, this is not the only problem you have. As pointed out with other post comments, your jQuery-centric approach is plain wrong. For more info take a look at this post: How do I “think in AngularJS” if I have a jQuery background?).
