Spinner not showing up for form_remote_tag in rails 2.3.11

Hi, I've a form_remote_tag as a part of my Rails 2.3.11 application. Upon form submit, ajax works appropriates. I use rjs to update the div with results.

However the spinner doesn't display.

Here's the code:

<% form_remote_tag :url => {:action => 'getHotels'},:loading => "$('spinnerBlock').show()",:complete => "$('spinnerBlock').hide()" do %>

..... .... <%= submit_tag 'Search ',:class =>"btn-112x22 mT10" %> <% end %>   <div id="spinnerBlock" style="display:none;">     <%= image_tag("/imagesA/ajax-loader.gif") %>   </div>

I've also tried following code:

<% form_remote_tag :url => {:action => 'getHotels'},:loading => "Element.show('spinner')",:complete => "Element.hide('spinner')" do %>

Any help is much appreciated.

Best, Navneet
