AngularJS directive that fixes the issue where browsers autofill inputs and they aren't reflective in the model upon submit.
Use bower install autofill-directive
Include in your javascript using require such as require('autofill-directive')(app);
Use the autofill-submit directive on the form that you are submitting and provide the angular expression you want executed. Then place the autofill directive on any inputs that may be autofilled by the browser. Now the model will be updated to reflect what the browser has autofilled into the input BEFORE the submit expression is executed.
<form autofill-submit="login()">
<input autofill ng-model="username" placeholder="Username" type="text" />
<input autofill ng-model="password" placeholder="Password" type="password" />
<input type="submit" value="Login" />
</form>
