Have you done any web development before using Wicket?
If so, you should be able to solve this problem by asking yourself the
following questions:
What happens if you click a link on a web page?
Do you think the browser sends the data in a text field on the page to
the server if you click a link?
What about if you put the <input> tag in a <form> and click a link?
What about if you put the <input> tag in a <form> and click a submit button?
In short, I'd suggest thinking a little more about the fundamentals
before playing around with user input in listviews. Have a look at the
examples.

P.S. There are ways to do what you're trying to do without needing to
put things in a form, etc., but they involve AJAX and therefore
probably aren't the best solution for whatever it is you're trying to
do.
