Unfortunately, what you want to do isn't possible.

The way Facebook Share is implemented means that it is effectively a data pulling mechanism with no interactive features. Every time someone loads your web page with a FB Share widget on it, the widget queries Facebook to get the latest "count". Essentially, whenever someone shares your page on Facebook, the URL is noted and a statistic counter for that URL is incremented. The widget you are rendering simply asks for that current count.

You can use the API Links.getStats callto get all of the information about a Share URL, but there is no scripting functionality available.
