Instead of binding the grid to a CFC directly, use the cfajaxproxy. Bind the grid to a JavaScript function, and set the grid's "bindOnLoad" attribute to true so it runs that JavaScript function when the Grid loads the first time. Then, in your JavaScript function, make a call to the CFC proxy and set up a callback handler. When the CFC returns the data, it will run the callback handler function. In the callback function, you can do whatever you want (look at the grid, look at the data that came back from the CFC, etc.) and render your count total. Full details on using cfajaxproxy can be found in the documentation.
