annotationClick event for Angular

[smithacigna]

I have a few charts, where I am using annotations to give extra information in almost a tabular form on the sides of a chart. I have tried a heat map, but I am not able to control the sizing and space. But annotations are flexible. On the fusions charts documentation, 'annotationClick' is mentioned, but it's not working when I try it. The 'dataplotClick' works just fine.
Is there a property or something I should be enabling before using the annotationClick, to get it to work?
the HTML:
<fusioncharts (renderComplete)="onRenderComplete($event)"
containerBackgroundOpacity="0"
width="100%"
height="250"
type="Column2d"
[dataSource]="datasrouce"
(annotationClick)="annotationClickEvent($event)"
