Regarding Freepbx IVR

in my freepbx I set up an IVR (Parent IVR)…Then pressing 1 in the Parent IVR takes me to Child IVR…I configured a callback as destination if I press 1 in Child IVR and i chose return to Parent IVR option also…So when I Press 1 in child IVR ,then it just takes me back to Parent IVR without executing the callback …

How to fix this.
