Calling model functions from views

[eluser]Unknown[/eluser]
I can't seem to do it. Every time I try, I get an error message like this:

A PHP Error was encountered

Severity: Notice

Message: Undefined property: CI_Loader::$mymodel

Filename: mymodel.php

Line Number: 5

Fatal error: Call to a member function hello() on a non-object in ~/public_html/codeigniter/system/application/views/content/form/forening_redigera.php on line 5

From the view file:

Code:

$this->load->model('mymodel');
echo $this->mymodel->hello();

From the model file:

Code:

function hello()
    {
        $hi = 'hello';
        return $hi;
    }
