How to create anchorage with on click?

I have a form built with ZK. This is the code:

<template name="model:group">
            <group label="@load(each)" onClick="@command('viewGraph', self=self)" onCreate="self.setOpen(false)" />
        </template>

In the bottom of the page I have a chart with an ID. In html if I write

Link

The focus of the page should be the element with id = chartID.

How can I do the same with zk and with onclick?
