Web API requests in 4.0 framework

I have to use the 4.0 framework to create a web API but I am not able to make a request:

public class ChartDataApiController : ApiController
{
    [HttpGet]
    public List<ChartDatum> GetData(int lowerBound, int upperBound)
    {
        return new List<ChartDatum>();
    }
}

I have this at the moment just to confirm that I can actually hit this action. The request:

var url = window.location.protocol + "//" + window.location.host + "/api/ChartDataApi/GetData";
$.ajax({
    url: url,
    type: "GET",
    data: {
        lowerBound: lowerBound,
        upperBound: upperBound
    },
    dataType: "json",
    success: function(response) {
         graph.draw(response);
    },
    error: function(message) {
         //error handler logic
    }
});

I just cannot hit this action. I have tried converting it to a POST just to see if I could get it to work but to no avail. Server error gives a 404 (had to modify in order to submit):

GET http:// (url) : port# /api/ChartDataApi/GetData?lowerBound=0&upperBound=29 404 (Not Found)

I can make a request just fine so long as I don't try to pass any parameters either via the query string or through the request body. I have also tried prefixing the parameters with the [FromUri] attribute but this also didn't work.

Here is the web api route config (simply the default):

public static void Register(HttpConfiguration config)
{
    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

I have made these sorts of requests before, but always in the 4.5 framework and think it may be a difference between frameworks.

You are requesting the wrong resource. In your case, you should issue a GET request to the /api/ChartDataApi endpoint.

HttpGetAttribute applied to the GetData method simply indicates that this method is responsible for hangling HTTP GET requests; there is no need to explicitly specify GetData method name in the request URI.
