ASP.NET web form - code behind function from html control

I want to know if it's possible to call a custom function in code behind from a html element. For example ASPX file

<a id="link" CustomAttributes="Custom Value" OnClick="link_click" runat=server>link</a>

ASPX.CS file

protected void link_click(object sender, EventArgs e)
{
  response.redirect("blabla.aspx?id="+link.Attributes["CustomAttributes"]);
}

Thanks, Mattia Quaglietta

I tried the code above but it doesn't work

Solution

Change onclick to onserverclick and make sure 'server' is in quotation marks.

<a id="link" CustomAttributes="Custom Value" onserverclick="link_click" runat="server">link</a>

protected void link_click(object sender, EventArgs e) {
  response.redirect($"blabla.aspx?id={link.Attributes["CustomAttributes"]}");
}
