Title: Add passing functions to charts

In this demo [jsfiddle](http://jsfiddle.net/gh/get/jquery/1.9.1/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/gauge-clock/) (line: 138) you can pass a function for some chart functionalty like that clock.

Would be nice to have this feature in your directive.
