Class method does not run when called upon in Kivy

I am new to kivy. I have created a login page with 2 text fields. I am now trying to pass the variables to the next page, which will use a ssh client for python to connect to a server. However, when I run the program, it seems that the method I am calling in my second screen does not even run, as none of the debugging output shows up.

I have tried a few methods of passing in variables into a function of a different class, and temporarily I have set upon using global variables. I am sure there is an easier or better way, but I can't get the function to run in the first place.

        ssh = paramiko.SSHClient()
        ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

        try:

            ssh.connect(host, port, username, password)

It seems that loading the Connect class is fine, however I am unable to run the .routine() method on_enter.
