Dashlets under the contact

When you open a client a bunch of tabbed bars like dashlits are below with the likes of invoices, quotes, so on. I have created a module called websites everything works fine. I just cant figure out how to change the info displayed in the open tab. at present it shows name and date modified. How and where can I change that.

I have attached an image of the tab opened to show you what Im talking about.

Thanks
