You'll have to recreate them after the post back.

To explain further.

When your code runs on the server it produces HTML output which is sent to the browser. At this point your server code ceases to exist - as far as the browser is concerned - only the resulting HTML / CSS / JavaScript is relevant.
This runs in the browser independently of the server code. Anything done by JavaScript is invisible to server code UNLESS the JavaScript tells the server what it has done by means of a callback - usually using AJAX.
When you postback to the server - the only information sent to the server is the information that the server setup in the first place. If you modified this in the browser with JavaScript - the server has no way of knowing that you did this - unless you tell it.

If you modify the view with JavaScript and you postback to the server then if you want to see the modifications
a) You have to pass this information back to the server - either in the Post Back or in an AJAX call
b) The server will need to use this information to render out the new content when it sends back its response.
