How to add save button in a form magento 1.9

Question

How can I add save button for each form and not one for all forms (as we have in magento by default)? I want something like that or into the form. I've tried this code

$fieldset->addField('yourfield', 'button', array(
'label' => Mage::helper('thorleif')->__('Button Labels'),
'value' => Mage::helper('thorleif')->__('Button Caption'),
'name'  => 'yourfield',
'style' => 'width:64px; height:21px;',
'class' => 'form-button',
'onclick' => "setLocation('{$url}')",
));

But I get a button without word like this

I've seen that always the value in html source code goes empty. So I've read that you have to change $form->setValues in your file by $form->addValues and it will work.
