Fatal error when using one module's controller action code in another module

Question

We are allowing guest to create an account with help of below function

<form action="<?php echo $this->getUrl('productlike/index/create', 
 array('_secure'=>(!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS']==='on'))) 
  ?>" method="post" id="ajaxlogin-create-form">

controllers

app/code/local/Outthink/ProductLike/controllers - Indexcontroller.php

class Outthink_ProductLike_IndexController extends Mage_Core_Controller_Front_Action  {
public function createAction(){  }
}

we are using same function code in another module as below, but its not working

<form action="<?php echo $this->getUrl('example/Amasty/create1', 
     array('_secure'=>(!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS']==='on'))) 
      ?>" method="post" id="ajaxlogin-create-form">

app/code/local/Amasty/Example/controllers - Amastycontrollers.php

class Amasty_Example_AmastyController extends Mage_Core_Controller_Front_Action {
public function create1Action(){  }
    }

Is this right way ? I dont want to rewrite same controller action because i need some other feature with the functions.

update

Fatal error Call to undefined method Amasty_Example_AmastyController::_getCustomer() in line $customer = $this->_getCustomer();

public function create1Action()

    {

        } 

        catch (Exception $e) {

           // $result['error'] = $this->__('Cannot save the customer.');
        }

        $this->getResponse()->setBody(Mage::helper('core')->jsonEncode($result));
    }

Please paste missing functions code in your controller file. The code is in other file.
