return json from Javascript to aspx with Ajax

I'm using .NET 4.5, I used this code from a WCF service to Javascript this worked fine. Now I can't seem to figure out how to send data back to the aspx page also with Ajax. What am I doing wrong?

Javascript called when pressing a button:

function sendEmeaDataToWcf(object) {
    $.ajax({
        type: "POST",
        url: "EditFeedEmea.aspx/UpdateEmeaData",
        data: JSON.stringify({ postData: "Test" }),
        processData: false,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        async: true,
        success: function() {
            console.log("Emea Data loaded");
        },
        error: showError
    });
}

The code in the code behind:

[WebMethod]
public void UpdateEmeaData(string postData)
{

}

He doesn't even get to the webmethod. I get a 500 error (jqXhr.status == 500). Receiving data from the same page works well. I also tried to remove processData, dataType, async, charset. Still nothing...

Your webmethod UpdateEmeaData needs to be static for this to work.

[WebMethod]
public static void UpdateEmeaData(string postData)
{

}
