Renaming workspaces interactively using DynamicWorkspaces does not work

I have been trying to find a way to rename workspaces while working. I'm currently using up to 4 workspaces at the time and I would like to assign the workspaces new names as needed. I came across XMonad.Actions.DynamicWorkspaces, and I am able to create and remove workspaces, however not rename. I have the current binding ((modM .|. shiftMask, xK_r), renameWorkspace defaultXPConfig) However when I enter something into the defaultXPConfig, nothing happens (and by nothing happens I mean, the name of the workspace doesn't change in my xmobar). I am able to create and delete workspaces, these changes appear in my xmobar. The method renameWorkspaceByName works as expected, therefore I believe I am using the xpconfig wrong? I have posted my xmonad.hs [here](https://pastebin.com/ZPF70Kgi )
