How to Add Custom MassAction In Controller For Status? 

My Status Having 

 1. Accepted
 2. Not Process
 3. Rejected
 4. Re-Offer

So how can I Get These Values in `change status` in MassAction? I Put Default MassAction But Getting "Enable" And "Disable" Value for the Status.

`MassAction`

    public function massStatusAction()
    {
    	
    	$pricenegotiateIds = (array)$this->getRequest()->getParam('id');
    	$pricenegotiateModel  = Mage::getModel('pricenegotiate/pricenegotiate')->load($pricenegotiateIds);
    		print_r($pricenegotiateIds);exit;
        $status     = (int)$this->getRequest()->getParam('status'); //get Status
    	if($status==2)
    	{
    		$couponcode=(rand(10,100));
    		echo $couponcode."<br>";
    	}
    	print_r($status);die;
        //your logic
    }
