Answer 1

First issue is you need a textbox with attribute name="empCode".
Second, you need to wrap the textbox in a form element.
Third, you need to post to the controller. Just changing the location in a button click (as you are doing) will do a get with no form data attached.
There are plenty of samples online which show this.
