Rather use <input type="submit">.

<input type="submit" name="bt" value="gi">

Its name/value pair will be sent to the server side as well:

String bt = request.getParameter("bt"); // gi

No need for JavaScript hacks/workarounds here. It would also break your application in case that the client has JavaScript disabled.
