javascript - Angularjs Chrome autocomplete dilemma

Question

I have a simple login form which works just peachy unless you use Chrome's auto complete feature.

If you start typing and use the auto complete feature and it auto populates your password, my angularjs model does not have any value for the password.

I tried to turn autocomplete off by setting the attribute on the form autocomplete="off" but that doesn't seem to have any effect.

How can I either: 1. Ensure that I can get the value if someone uses Chrome's auto-complete feature? 2. Disable Chrome's auto-complete feature?

<form class="form-signin" name="form" ng-submit="login()" autocomplete="off">

        <h3>Login</h3>

        <input type="email" name="email" class="form-control" placeholder="Email address" ng-model="user.email" required autofocus>
        <input type="password" name="password" class="form-control" placeholder="Password" ng-model="user.password" required>

        <button class="btn btn-lg btn-primary btn-block" type="submit">Sign in</button>

 </form>
