Hi Varun,
You can acheive this with some Jquery and the javascript snippet widget.
Put the javascript snippet with datasource widget inside a dataview.
Create an attribute to use in the script.
Then add something similar to this in the javascript section (make sure to enable jquery).
jQuery(document).ready(function() {
setTimeout(function() {
document.title = '${variable}';
}, 100);
});
Hope this helps!
