Load views in Controller or Model?

[eluser]flacznik[/eluser]
Yesterday i red a book where the writer advise to load a view inside a model. Then simply call the function in controller like to show the page:

Code:

$this->load->model('display');
$this->display->mainpage($data);

The question is - which way is more proper, to load the views inside controller or model? In my opinion is quite interesting to build the view inside a model...
