why I can't embed my template in the main theme in prestashop 1.7?

[medoampir]

I'm trying to follow the official guide of prestashop but I am facing 2 issues:

1. I see the display.tpl as raw text and not embedded in the main theme.
2. I can't see the message stored in the variable "my_module_message"

 

mymodule.php
 

public function hookDisplayLeftColumn($param)
	{
		$this->context->smarty->assign(
			array(
				'my_module_name' => configuration::get('G2A_NAME'),
				'my_module_link' => $this->context->link->getModuleLink('g2a','display'),
				'my_module_message' => $this->l('This is a simple text message')));

		return $this->display(__FILE__ , 'g2a.tpl');
	}

controllers/front/display.php

class g2adisplayModuleFrontController extends ModuleFrontController
{
  public function initContent()
  {
    parent::initContent();
     $this->context->smarty->assign('my_module_message', $this->l('This is a simple text message'));
        $this->setTemplate('module:g2a/views/templates/front/display.tpl');
  }
}

views/templates/front/display.tpl

{extends file=$layout}

{block name='content'}
  welcome to my shop!
  {$my_module_message}
{/block}

HI

 

1  you are on 1.7 you need extend the structure of the tpl  for example

{extends file='page.tpl'}

 

2 because you are not send any information you need set the smarty on the frontcontroller
