How to wrap radio button group in label zend form - zend-framework

Question

I want the following html with two radio button groups in zend form
<label class="inline">
<input type="radio" name="form-field-radio">
<span class="lbl"> Male</span>
</label>
<label class="inline">
<input type="radio" name="form-field-radio">
<span class="lbl"> Female</span>
</label>
and i'm using the following code to make this button in Zend Form
$gender = $this->CreateElement('radio','gender')
->addFilter(new Zend_Filter_StringTrim())
->setMultiOptions(array('M'=>'Male', 'F'=>'Female'))
->setDecorators(array( array('ViewHelper') ));
But I don't know where to set the lable and span classes in this code.
Please help.
Thanks.

I am not sure whether its the perfect method to do this its the first time i am using zend framework, But still here are the steps that i did, if you may find useful:
First I created a custom decorator which extends Zend_Form_Decorator_Abstract and saved it in the location 'decorator/My_Form_Decorator.php'. decorator is a directory created by me in root.
.
/decorator
/application
etc...
Then i included it in a controller. I have read that there are certain methods for adding the decorator like addPrefixPath() but for time sake i just included the decorator file in top with 'include "../decorator/My_Form_Decorator.php";'. Then instead of using the CreateElement method i used Zend_Form_Element.
The following is the code of custom radio decorator
My_Form_Decorator.php
class My_Decorator_RadioInput extends Zend_Form_Decorator_Abstract
{
public function render($content)
{
$element = $this->getElement();
$label = htmlentities($element->getLabel());
$type = $element->type;
$name = $element->elemName;
$multiOptions = $element->multiOptions;
$labelClass = $element->labelClass;
$spanClass = $element->spanClass;
$markup='';
if(!empty($type) && !empty($name) && !empty($multiOptions) && is_array($multiOptions)){
foreach($multiOptions as $key=>$value){
$markup .='<label class="'.$labelClass.'"><input type="radio" name="'.$name.'" value="'.$key.'"> <span class="'.$spanClass.'">'.$value.'</span></label>';
}
}
return $markup;
}
}
and this is the code in my controller function
IndexController.php
$decorator = new My_Decorator_RadioInput();
$form = new Zend_Form();
$form->setAttrib('id', 'test');
$element = new Zend_Form_Element('foo', array(
'elemName'=>'gender',
'type' =>'radio',
'multiOptions' => array('M'=>'Male', 'F'=>'Female'),
'labelClass'=>'inline',
'spanClass'=>'lbl',
'decorators' => array($decorator),
));
$form->addElement($element);
$this->view->form = $form;
And in view index.phtml
echo $this->form
Hope this is helpful to you..
