Adjustable textinput in kivy scrollview - python-3.x

Question

I am new to Kivy. I would like multiple textInputs to be displayed properly inside the Kivy scrollView dynamically where the textInput size fits the content. The current code displays only 3 as the height of the gridLayout is set to 1000. I would like to use height: self.minimum_height so that I can dynamically add more textInputs and they will be displayed properly, however but cannot seem to get it working.
My kv file:
<MyNote#BoxLayout>:
orientation: 'vertical'
TextInput:
height: self.minimum_height
multiline: True
text_size: self.size
size_hint_y: None
text: '1\n2\n3\n4\n5\n6\n7\n8\n9\n10\n11\n12\n13\n14\n15'
<MainNotesBoxLayout>
orientation: 'vertical'
ScrollView:
GridLayout:
cols: 1
size_hint_y: None
height: 1000
#height: self.minimum_height
MyNote:
MyNote:
MyNote:
My main file:
import kivy
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
class MainNotesBoxLayout(BoxLayout):
pass
class NotesApp(App):
def build(self):
return MainNotesBoxLayout()
if __name__ == '__main__':
NotesApp().run()

Replace GridLayout with BoxLayout
Set the minimum height of the boxlayout so that there is something to scroll.
ScrollView
layout.bind(minimum_height=layout.setter('height'))
Example
notes.py
from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput
from kivy.properties import ObjectProperty
class MyNote(TextInput):
pass
class MainNotesBoxLayout(BoxLayout):
container = ObjectProperty(None)
def __init__(self, **kwargs):
super(MainNotesBoxLayout, self).__init__(**kwargs)
self.container.bind(minimum_height=self.container.setter('height'))
self.add_text_inputs()
def add_text_inputs(self):
for x in range(100):
my_note = MyNote()
self.container.add_widget(my_note)
class NotesApp(App):
def build(self):
return MainNotesBoxLayout()
if __name__ == '__main__':
NotesApp().run()
notes.kv
#:kivy 1.10.0
<MyNote>:
height: self.minimum_height
multiline: True
text_size: self.size
size_hint_y: None
text: '1\n2\n3\n4\n5\n6\n7\n8\n9\n10\n11\n12\n13\n14\n15'
<MainNotesBoxLayout>
container: container
orientation: 'vertical'
ScrollView:
size_hint: (1, 1)
bar_width: 10
bar_color: 1, 0, 0, 1 # red
bar_inactive_color: 0, 0, 1, 1 # blue
effect_cls: "ScrollEffect"
scroll_type: ['bars']
BoxLayout:
id: container
orientation: 'vertical'
size_hint: 1, None
Output
