Bundle javascript in partial view to use as widget

Hi All,

I would like to create a small widget where it contains a search box a submit button and 3 labels and 3 texboxes for displaying employee name , email, phone number. So whenever employee id is entered and upon clicking submit button I would like to make an ajax call to my controller and get the details and fill the partial view. I do not want the ajax call in main view because that will not enable me to use it in other views.

How do I achieve this? Thanks for your time.
