Why my model function doesn't work in ZEND? -

i'm wondering wrong code : function controller :

public function testareaction(){      // $this->getresponse()->setheader('content-type', 'application/json');     $this->_helper->layout->disablelayout();     $this->_helper->viewrenderer->setnorender(true);     //$myarray =  $_post['data_post'];     //$product_ids = $_post['product_ids'];     //$type = 1;     $model = new application_model_order();      echo $model -> saveordernames(); } 

and function model :

public function saveordernames(){     return 1; } 

why im not getting result "1" in browser?
im newbie please give me speficitions.

thx :d index controller :

public function indexaction()     {         if (!($locationurl = $this->_getparam('locationurl'))) {             throw new \zend_controller_action_exception('location url not provided.', 404);         }                  $this->maidivclass = "block clear step1";          // location row         $mapper = new dbtable\location();         $sql = $mapper->select()->where('url = ?', $locationurl);          if (!($this->view->location = $mapper->fetchrowactive($sql))) {             throw new \zend_controller_action_exception('location not found', 404);         }          // set active markup location menu         $this->_helper->layout()->locationmainmenuurl = $this->view->location->url;          // seo         $this->setseo(             $this->view->location->meta_title,              $this->view->location->meta_description,              $this->view->location->meta_keywords         );          // day param         $dayname = $this->_getparam('day', cronos::getcurrentdayname());          $this->view->dayno = cronos::getweekdaynumber($dayname);         if ($this->view->dayno === false) {             throw new \zend_controller_action_exception('invalid weekday provided.', 404);         }          $this->view->selecteddate = cronos::getdatewithoffset($this->view->dayno); // date offset         $this->view->categmapper  = new dbtable\categories();          $appcfg = new zend_config_ini(application_path .

ok , created in models folder file : ordernames.php , model contains :

<?php     class ordernames {          public function saveordernames(){                  return 1;                 }      }    ?>  

and function controller :

public function testareaction(){          $this->_helper->layout->disablelayout();         $this->_helper->viewrenderer->setnorender(true);         echo "1tralala";         $model = new application_model_ordernames();          echo "2<hr>";         $model -> saveordernames();  } 

why string "2tralala" doesnt appear ?

you call: $model = new application_model_ordernames();
name of php file ordernames.php
, class is

class ordernames {      public function saveordernames(){              return 1;             }  }    

so try replace name of class:

class application_model_ordernames {...
