getJSON is not calling the controller action

I don't know why this is happening since there are other functions in this page that use also getJSON and they do work. I have the following JavaScript Code

function openSOPNotesDialog() {

        var url = '<%: Url.Action("GetSOPNote", "SalesOrder") %>';
        var id = <%: Model.SodID %>;

        $.getJSON(url, { sodId : id }, function(data) {
            alert("data: " + data);
            $("#hidSOPSODId").val(data.SodID);
            $("#hidNoteId").val(data.NoteID);
            $("#txtSOPNotes").val(data.Description);
            $("#sopNotesDialog").dialog("open");
        });

    }

and then I have this method on the SalesOrderController class

public JsonResult GetSOPNote(int sodId)
        {
            var service = new SodSrv();
            var note = service.GetSOPNotes(sodId);
            return Json(note, JsonRequestBehavior.AllowGet);            
        }

However, the method is never called in the debugger and data is returned as null (which is what I'd expect). As I said before there are other calls in this page and they are also doing GET requests so I don't know what may be the cause.

I suspect that the reason is that getJSON uses get method and controllers normally allowed to accept only post methods. It's ease to check using any browser firebug for example.

Sounds like the browser is pulling the data from the cache since it is a get request. Make sure to set no cache headers on the server if it is not meant to be cached.

Try adding an error handler to try to track down what the issue is:

$.ajax({
    dataType: 'json',
    url: url,
    data: { sodId : id },
    success: function(data) {
        alert("data: " + data);
        $("#hidSOPSODId").val(data.SodID);
        $("#hidNoteId").val(data.NoteID);
        $("#txtSOPNotes").val(data.Description);
        $("#sopNotesDialog").dialog("open");                        
    },
    error: function(jqXHR, textStatus, errorThrown) {
        alert("oops: " + textStatus + ": " + jqXHR.responseText);
    }
});
