title: Discord Bot does not respond to commands
body: <p>I've been developing a discord bot for the past month, I've been doing commands using on_message listeners, which according to alot of people online isn't very ideal, so I decided to take it to the next step and do it properly, I looked at the documentation and came up with this basic code:</p>
  
  <pre><code>import discord #import all the necessary modules
  from discord import Game
  from discord.ext import commands
  
  client = discord.Client() #define discord client
  bot = commands.Bot(command_prefix='!') #define command decorator
  
  @bot.command(pass_context=True) #define the first command and set prefix to '!'
  async def testt(ctx):
      await ctx.send('Hello!!')
  
  @client.event #print that the bot is ready to make sure that it actually logged on
  async def on_ready():
      print('Logged in as:')
      print(client.user.name)
      await client.change_presence(game=Game(name="in rain ¬ !jhelp"))
  
  client.run(TOKEN) #run the client using using my bot's token
  </code></pre>
  
  <p>Before going through the pain of implementing all of my commands to this new way of doing things, I wanted to test it so I know that it works for sure and sadly, it didn't, I went through a bunch of posts and documentation again but I couldn't spot what I did wrong, the bot logs in fine to the proper user and I just can't seem to figure out and understand what the problem is, I am probably missing something obvious yet again</p>
  
  <p>Could anyone help, that would be great, thank you!</p>
