<h3>@OnEvent</h3>
If you prefer, you can annotate event handler methods with <code>@OnEvent</code> rather than use the "on" naming convention.
<div class="eg">
Count = ${count}.<br/>
<t:eventlink t:event="add" t:context="literal:1">Add 1</t:eventlink><br/>
<t:eventlink t:event="add" t:context="literal:2">Add 2</t:eventlink><br/>
<t:eventlink t:event="clear">Clear</t:eventlink>
</div>
