Html.Partial() skips the controller action

I am using @Html.Partial(“Index”) to call upon an action called “Index” in a controller, which should then return me the “Index” view. Unfortunately, it looks like the controller action is ignored because I get an error in Index view that Model is null. I tried setting breakpoints in the controller action and they are simply being skipped, it seems that the view “Index” is rendered without reading the controller? What is going on here?
