I wrote few custom view helpers but I have a little trouble using them. If I add the helper path in controller action like this:

public function fooAction()
{
    $this->view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

Then I can use the views from that path without a problem. But when I add the path in the bootstrap file like this:

protected function _initView()
{
    $this->view = new Zend_View();
    $this->view->doctype('XHTML1_STRICT');
    $this->view->headScript()->appendFile($this->view->baseUrl()
                                          . '/js/jquery-ui/jquery.js');
    $this->view->headMeta()->appendHttpEquiv('Content-Type',
                                       'text/html; charset=UTF-8');
    $this->view->headMeta()->appendHttpEquiv('Content-Style-Type',
                                             'text/css');
    $this->view->headMeta()->appendHttpEquiv('Content-Language', 'sk');
    $this->view->headLink()->appendStylesheet($this->view->baseUrl()
                                              . '/css/reset.css');
    $this->view->addHelperPath('My/View/Helper', 'My_View_Helper');
}

Then the view helpers don't work. Why is that? It's too troublesome to add the path in every controller action. Here is an example of how my custom view helpers look:

class My_View_Helper_FooBar
{
    public function fooBar() {
        return 'hello world';
    }
}

I use them like this in views:

<?php echo $this->fooBar(); ?>

Should I post my whole bootstrap file?

UPDATE:

Added complete bootstrap file just in case:

            'My/Controller/Action/Helper',
