• I replaced my code with your, but not working for me. – Vijaya Savant Commented Apr 28, 2015 at 11:02
• What does html() function do? Shouldn't that just be $('#data_btn').attr('title', returndata); – Shaunak D Commented Apr 28, 2015 at 11:03
• Are you even getting into success: parameter?? – Dhaval Marthak Commented Apr 28, 2015 at 11:03

if you want to use $('#data_btn').title = returnData;, do this: $('#data_btn')[0].title = returnData;, html() is undefined, so just assign returnData to your title

jsfiddle

by trying below code, it works for me.

$('#data_btn').attr('title',returndata);

You never use .title = html(returndata); the = sign in a jQuery chain... also, .title() is not a function.

Use the following:

$('#data_btn').attr('title', $(this).html(returndata));
