socketio.emit() not working

hey I need the server to be the originator of a message when an entry is inserted into the database. I have this line in my app.py file

@app.route('/pet', methods=['GET'])
def insertPet():
...conducting insert in database...
socketio.emit('inserted_pet', {details: details}, broadcast=True)
return render_template('index.html')

on subscribe.html (using angularjs) where I have registered a listener as follows: socket.on('inserted_pet', function(results){ console.log(results); }); All I see are some http 400 errors in the browser console. Nothing shows up… now the thing is… on connect works so this means I have things correctly set up:

@socketio.on('connect')
def on_connect():
    emit('test', {"test": "lmao"}, broadcast=True) 
    pass

in subscribe.html:

socket.on('connect', function() {
	socket.emit('connect');
});
socket.on('test', function(results){
	console.log(results);
});
