Tabs - GetActiveTab

[lartusi]

I'm trying to dynamically change the title of the page when entering on a new tab.
<h1>@tabs.GetActiveTab()?.Title</h1>

Unfortunally this is not working.
Can you suggest me how I can achieve this?

Actually i'm using a variable and i call the onclick event on every tab to populate this variable.
I'm wondering if there could be a smarter way to do the same.
