A quick and easy answer I'm sure. 
I'm upgrading a Rails project from version 2 to version 3 and replacing a load of the link\_to\_remote with link\_to's as per the Rails 3 update. Even something as simple as :

```
<%= link_to "Check Time",
        {:action=>:get_time}, :remote=>true, :update=>'current_time' %>
<div id='current_time'></div>

```

doesn't seem to work. The request (using get method) is going through ok and the rendered html is :

```
<a href="/monitoring/get_time" data-remote="true" update="current_time">Check Time</a> 

```

Routes.rb entry : 

```
get "monitoring/get_time"

```

As I say I'm sure this is a very obvious issue on my part!
