Adding a button to the CMS in SilverStripe

Question

How do I add a button to the backend of the CMS that fires an action? I can display the button where I want using:

public function getCMSFields()
{
    $fiel

Not sure if this is helpful, but here's how you can add action-buttons to a ModelAdmin.
(does reload the page)

...in the admin class:

public function getEditForm($id = null, $fields = null)
{
    $form = parent::getEditForm($id, $fields);
    $form
        ->Fields()
        ->fieldByName($this->sanitiseClassName($this->modelClass))
        ->getConfig()
        ->getComponentByType('GridFieldDetailForm')
        ->setItemRequestClass('MyGridFieldDetailForm_ItemRequest');

    return $form;
}

MyGridFieldDetailForm_ItemRequest.php

class MyGridFieldDetailForm_ItemRequest extends GridFieldDetailForm_ItemRequest
{
    function ItemEditForm()
    {
        $form = parent::ItemEditForm();
        $formActions = $form->Actions();

        $button = FormAction::create('myAction');
        $button->setTitle('button label');
        $button->addExtraClass('ss-ui-action-constructive');
        $formActions->push($button);


        $form->setActions($formActions);
        return $form;
    }

    public function myAction(){ //do things } 

}
