How to get value of text input kivy?

Question

Python

I have already used text input, but this time I am forced to look for a solution here. I tried using id: ... but
no luck
:
size_hint_y: 0.2
text: 'get links'
on_press:
self.FROM = 'lon' # this works
self.TO = 'par' # this works
#self.FROM = from_ .text ############ cannot get this value
#app.TO = to_.text ####
#self.links_grid.clear_widgets()
#self.clear_widgets()
self.SEARCH()
Here is the code:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
from kivy.app import App
from kivy.uix.button import Button
from kivy.lang import Builder
class GetLinksButton(Button):

t = '''
'Driver Pego', 'London - Paris'
'Driver Pego', 'London - Sidney'
'Driver Pego', 'London - Rom'
'Driver Pego', 'Vena - Paris'
'Driver Pego', 'Goa - Paris'
'''
self.DRIVES = t.read().split("\n")
link_number = 1
def get_links(self):
self.links_grid.clear_widgets(self.children)
self.link_number = 1
for i in self.DRIVES:
print(i)
try:
i = ','.join(i)
except:
pass
link_button = LinkButton(
text=str(self.link_number) + ' / ' +
" / ".join(i.split(","))
)
self.link_number += 1
self.links_grid.add_widget(link_button)
