Openstack Cloud Provider

Hey, I want to ask a question regarding openstack cloud providor. I have sync all the data by adding cloud providor of openstack into manageiq. I can provision vms through provision lifecycle. i have created service of vm but the problem is when i go to self_service or from service catalog i order the service it directly launches instance it does not ask parameters such as vm name security group and other stuff it ask on the time of service catalog creation i have inserted that now i want to customize that info when the user will order the service ? can any one guide me what to do ? i have just added providor of openstack .
