AngularJS bind $scope data to form - angularjs

Question

I have a $rootScope variable:
$rootScope.register_data = {};
I have a view which contains a form:
<form name="register_data">
<div class="popup signup">
<div class="social">
<a ng-controller="FacebookCtrl" ng-click="login()" href="javascript:void(0)" class="facebook fb-login-button">Sign up with Facebook</a>
<div class="clear"></div>
</div>
<div class="userinfo">
<div class="left"><input type="text" ng-model="register_data.firstname" placeholder="First Name" tabindex="1" required></div>
<div class="right"><input type="text" ng-model="register_data.email" placeholder="Email Address" tabindex="4" required></div>
<div class="left"><input type="text" ng-model="register_data.lastname" placeholder="Last Name" tabindex="2" required></div>
<div class="right optional"><div class="tip">optional</div><input type="text" ng-model="register_data.dob" tabindex="5" placeholder="DoB (dd/mm/yyyy)"></div>
<div class="left"><input type="text" ng-model="register_data.phone" placeholder="Phone Number" tabindex="3" required></div>
<div class="right password"> <input type="password" ng-model="register_data.password" placeholder="Password" tabindex="6" required></div>
<div class="clear"></div>
</div>
<div class="control">
<span class="terms">I agree to the terms & conditions</span>
Sign up
</div>
</div>
</form>
The form has a name register_data and each field is bound to that via ng-model. It seems to overwrite my $rootScope.register_data variable as when I update that none of the form controls update. Though if I remove the form name then it works. However i need the form name to do proper form validation.
Anyone know how I can bind the form controls to a scope object but also keep the form validation?

Answer 1

Change the form name to be something else other than the name used as model, since the form controller will be published into related scope, under this name.
