Add an initial value for your ng-model , then use ng-class to set dynamic classes

View

<div ng-controller="TabsCtrl">
  <div class="tabbable" ng-model="currentTab">
    <div class="tab-pane" ng-class="{'special-class': currentTab == 1}" title="1" value="1">
      Content 1
    </div>
    <div class="tab-pane" title="2" value="2">
      Content 2
    </div>
  </div>
</div>

Controller

var app = angular.module('plunker', ['bootstrap']);

app.controller("TabsCtrl", function($scope) {
  $scope.currentTab = 1;
});
