You can use ng-click to change values on your scope prior to submission

<form ng-submit="submit()" ng-controller="Ctrl">
  <input type="submit" ng-click="setAtts('A', 'B')" value="Edit" />
  <input type="submit" ng-click="setAtts('C', 'D')" value="Delete" />
</form>

<script>
  function Ctrl($scope) {
    $scope.submit = function() {
      alert($scope.att1);
      alert($scope.att2);
    };

    $scope.setAtts = function(a1, a2) {
      $scope.att1 = a1;
      $scope.att2 = a2;
    };
  }
</script>

Edit: As a side note $event will not work for ng-submit, if you're interested in using $event.target (which probably shouldn't be done from a controller anyhow)
