I haven't closely followed what else you're doing here, but this
definitely looks wrong -- I think you meant to do

  $ echo "24c64 0x50" > /sys/bus/i2c/devices/i2c-3/new_device

Note the position of the close quote -- as you had it above it's just
writing a long string to stdout instead of sending the device name and
i2c address to the sysfs 'new_device' file.
