# This gist shows how to display Rails like flash messages while handling AJAX or JS requests
# Note - This might not be the best way to do this but it works for me

Step 1. Create a partial which will contain the message to be displayed
        Example - _success.html.erb
        <div id="flash_message">
          <p>Success</p>
        </div>

Step 2. In the Controller, add code to call this partial on a JS request
