Blazor onchange event with select dropdown

So I have been stuck trying to get a simple onchange to fire when a select dropdown value changes. Like so:

<select class="form-control d-flex" onchange="(dostuff())">
    @foreach (var template in templatestate.templates)
    {
        <option value=@template.Name>@template.Name</option>
    }
</select>

with the method being called:

void dostuff()
{
   Console.WriteLine("first spot is firing");
    _template = templatestate.templates.FirstOrDefault(x => x.Name == 
    _template.Name);
    Console.WriteLine("second spot is firing");
}

The result I get it no matter how I try to reorient it is this error in the browser.

Uncaught Error: System.ArgumentException: There is no event handler with ID 0

Is there something obvious and key that I am missing? Because I have a button onclick event that works just fine on the same page.
