Angular ng-submit called twice

I have an angular form whose submit method is being hit twice, and I can't figure out why. I'm pretty new to Angular, so it's possible I'm overlooking something fairly simple...

Html:

<div ng-app="RegistrationApp" ng-controller="RegistrationController">
    <form name="accountForm" ng-submit="submitAccount($event, accountForm, account)"  novalidate>

        // inputs here...

        <button type="submit" class="btn btn-success pull-right" ng-disabled="accountForm.$invalid">Submit</button>
    </form>
</div>

Js:

var RegistrationApp = angular.module('RegistrationApp', []);

RegistrationApp.controller('RegistrationController', function ($scope) {

    $scope.submitAccount = function (evt, form, account) {
        console.log('submitAccount() hit'); 
        console.log(evt);
        console.log(form);

        evt.stopPropagation();

        // AJAX code
    });
});

Console Window:

submitAccount() hit 
o.Event {originalEvent: Event, type: "submit", isDefaultPrevented: function, timeStamp: 1394139847226, jQuery210012237170152366161: true…}
c {$error: Object, $name: "accountForm", $dirty: true, $pristine: false, $valid: true…}

submitAccount() hit 
o.Event {originalEvent: Event, type: "submit", isDefaultPrevented: function, timeStamp: 1394139847226, jQuery210012237170152366161: true…}
Constructor {$error: Object, $name: "accountForm", $dirty: true, $pristine: false, $valid: true…}

So, the first thing I tried was to stop propagating the event, but that doesn't have any real effect. After going through the event objects, they're seem identical. The only thing that differs is the 'form' object. The properties are the same, except that one shows that "c" and the other shows "Constructor".

Any ideas what could be causing this to trigger twice? The event target is set to the form element in both cases, and I'm not using any onclick functions, or any other sorts of events in the form.

Check you didn't declare your controller twice: one in the HTML, as I can see above, and another when configuring your routes. If it's the case, the controller is instanciated twice, so the listener is invoked twice
