I have a visualforce page which shows list of a custom object records.One column shows the Account name which has lookup relationship with the custom object.I need to add one button in each row and on click this will show the contact records for that account only in a different vf page.I have tried passing the account id in the vf page that I have created for contact list.But it gets redirected to account record.

Thanks for help!

//custom object records
        public List getCustomObjectRec()
        {
        return (List) setController.getRecords();
        }
        //page reference
        public PageReference showContacts(){       
        PageReference pr = Page.MyContactListPage;
        pr.getParameters().put('accountId','Account ID');
        return pr;
        }
