One way is to add the following below balance_div:
<%= javascript_tag "$('guarantee_status').onchange()" %>
Another would be to only render display:none into the
div tag if the condition is met.
The first method is preferred because when a page is
refreshed in Firefox it does not reset form entries,
but your app is still called as a simple GET, so the
div may be inappropriately made visible or hidden.
