How to change the squad parameter of ticket from FB Python API

Question

I am using Fogbugz Python API, and I want to change the squad parameter of my ticket.

Did the below change through Fogbugz UI.

<sChanges>
Squad changed from (No Value) to 'x'.
</sChanges>

but when I am doing,

fb.edit(ixBug=75268,sSquad="Security and Compliance")

It does not seem to change anything, anyone knows how to go about it? How do I make the change to squad?
