Trying for nifty intraday but getting error.

I have been trying to place a BUY oder throug publisher button but I am facing error but for RELIANCE it is working fine.
Can someone please help me with the right format. What I am trying to do is
BUY 11600 CALL Option for 11th April expiry.
My format is --

<script src=""></script>


KiteConnect.ready(function() {
var kite = new KiteConnect("14tmno**********");

// Add a Bracket Order
"tradingsymbol": "NIFTY11APR11600CE",
"exchange": "NFO",
"transaction_type": "BUY",
"order_type": "MARKET",
"product": "NRML",
"quantity": 75,
"readonly": false

// Register an (optional) callback.
kite.finished(function(status, request_token) {
alert("Finished. Status is " + status);

// Render the in-built button inside a given target

// OR, link the basket to any existing element you want"#custom-button");
