 Next we will add both a Detail and Footer template. For Ajax functionality we will call OWS.Fetch, which makes an AJAX request to the server, and expects in return markup which is to be both written tot he page and parsed for javascript tags. we will want the result of that fetch to be a Script execution, and it should not visually affect the displayed front end. To do this, we will need to pass a targetid to the AJAX request, that target being the location where the result should be rendered. In the footer template, add a dummy Div which will be used to contain the result. I normally give it an id like 'dvHidden', and a style setting it to display none.
