JTemplates template file cached workaround

I've been using a lot of JQuery and JTemplates after reading a couple really helpful JQuery and MVC posts at Encosia.com. One problem I ran into while doing some development on a new .Net MVC Project that was using JQuery extensively was that my template files were being cached by my browser. I tried clearing the cache but that wasn't helping, so here's a workaround I came up with.

If you take a look at how JQuery's $.ajax(...) function handles the caching problem you can see that they append a random query string parameter to each request.

So that is what I basically did to workaround the caching problem with the template files. I created a function called cacheBust() that just returned the current times milliseconds value and used that to generate my random query string. Here's some sample code:

function cacheBust() {return new Date().getMilliseconds().toString();}

function GetTimeEntries(day) {
   // Show the loady
   showLoady();

   $.ajax({
   type: "GET",
       cache: false,
       url: "/TimeEntry/" + day.replace(/\//g, "-"),
       contentType: "application/json; charset=utf-8",
       dataType: "json",
       success: function(msg) {
           // This method loads the HTML template and
           //  prepares the container div to accept data.
           $('#TimeWrapper').setTemplateURL('/scripts/timeentry.vw?_=' + cacheBust());

           // This method applies the JSON array to the 
           //  container's template and renders it.
           $('#TimeWrapper').processTemplate(msg);

           // Hide the loady.
           hideLoady();
       },
       error: function(XMLHttpRequest, textStatus, errorThrown) {
           // typically only one of textStatus or errorThrown 
           // will have info, I'm not using either.
           hideLoady();
           $('#TimeWrapper').empty();
           $('#TimeWrapper').append("<p class='errord'>There was a problem loading the data from the server.  Sorry I got nothing else.</p>");
          
       }

   });
}

And now we get the most up to the second versions of our templates. Once I'm done with development it will be beneficial to have the templates be cached. I figure once that happens I'll change my cacheBust() function to return a constant (something like, "ItCompilesSoShipIt").
