How to add a hotplug to make symlink?

To make a symlink between /proc/device-tree/aliases/serial1 ->/dev/ttyAMA0.For that i have tried one script in /etc/hotplug.d/uart/99-com,which is as follows.

#! /bin/sh

if[ "${ACTION}" = "add" ]; then
                logger -t To create Hotplug Symlink
                DEVICE_NAME=$(cat /proc/device-tree/aliases/serial1)
                ln -s /dev/$DEVICE_NAME /dev/${SYMLINK}
                logger -t Symlink from /dev/$DEVICE_NAME to /dev/${SYMLINK} created.

Can anyone please tell me what is the mistake I am doing here because of that symlink is not happening.
