First, you're using Html.Action which causes a child action to be rendered where it's called. It looks like you're looking for Url.Action or Html.ActionLink.

Second, that code is not even correct. The value of onclick must be some JavaScript expression. All you're passing is just a URL, which without quotes, is not even valid JavaScript. If you did add quotes, then it's just a JavaScript string, which won't do anything on its own.

Third, I'm not sure why you're even doing it that way, as your button here is a submit button, so assuming both this button and the field is wrapped in the same form element, then it works out of the box - no need for onclick or any JavaScript at all.

Finally, it seems you don't understand how client-server works. Razor (your @Html.Action) is processed server-side, while the field's value won't be set by the user until it's already been rendered by the server and sent to the client (the web browser) as a response. Therefore, there's no way to access the user's input before the user has even seen the form, let alone input anything.
