How to use partially parameterized functions or class methods as ticker callbacks

I'm building a basic application and need some instance level control on the ticker, thus I'm trying to use class methods or even partially called functions to set callbacks for the ticker, but they are not working.

Using class methods, my code looks like this :

import pandas as pd
from kiteconnect import KiteTicker

class TICKER:
	def __init__(self, instruments, api_key, access_token):
		self.instrument_ticker = KiteTicker(api_key, access_token)
		self.instruments = [int(v) for v in instruments.values()]
		self.set_instrument_ticker_callbacks()
		self.instrument_ticker.connect()

	def connect_indices(self):
		def on_connect(ws, response):
			ws.subsribe(self.instruments)
			ws.set_mode(ws.MODE_FULL, self.instruments)
		return on_connect

	def print_instrument_ticks(self, ticks):
		curr_prices = [i['last_price'] for i in ticks]
		self.subscribe_levels(curr_prices)
		print(ticks)

	def subsribe_levels(self, curr_prices):
		return

	def instrument_ticks(self):
		def on_ticks(ws, ticks):
			self.print_instrument_ticks(ticks)
		return on_ticks

	def instrument_ticker_close(self):
		def on_close(ws, code, reason):
			self.print_instrument_ticks(reason)
			ws.close()
		return on_close


	def set_instrument_ticker_callbacks(self):
		self.instrument_ticker.on_connect = self.connect_indices()
		self.instrument_ticker.on_ticks = self.instrument_ticks()
		self.instrument_ticker.on_close = self.instrument_ticker_close()

And using partial functions, it looks like this :

import pandas as pd


def on_instrument_connect(instruments):
    def on_connect(ws, response):
        ws.subsribe(instruments)
        ws.set_mode(ws.MODE_FULL, instruments)

    return on_connect


def on_instrument_ticks():
    def on_ticks(ws, ticks):
        print(ticks)
        # Do Other Shit
    return on_ticks


def on_instrument_close():
    def on_close(ws, code, reason):
        ws.stop()

    return on_close

But using both these methods, i get :

Connection error: 1006 - connection was closed uncleanly (I dropped the WebSocket TCP connection: 'KiteTicker' object has no attribute 'subsribe')

But if i use simple methods, it works fine.
What am i doing wrong?
