You can do this:

     (function(angular) {
        angular.module('controllerExample', [])
          .controller('myctrl', ['$scope', myctrl]);
        function myctrl($scope) {     

    $scope.example=function example(){

         //your code will be  here 
       }

    function example2(){
      //do your code. You can call this function only in this controller.
    }
  example2();

    }
})(window.angular);

You can call example() from your template.
