AJAX and c# mvc controller get bool

Question

I have been stuck at this for some time now. I am trying to send a bool from my controller to the view through ajax. I tried several different tutorials and methods but can't seem to be able to retrieve some simple data. I was hoping somebody can explain what am I doing wrong.

Here is my code:

Ajax:

$(document).ready(function () {

$.ajax({
    "url": "/social/checkfollow",
    "type": "GET",
    "dataType": "json",
    "success":function(data) {

        console.log(data);
    },
    "error": function(data) {
        console.log(data.status +" "+ data.statusText);
    }
});

});

And the controller:

   [HttpGet]
    public virtual ActionResult CheckFollow()
    {
        var pass = false;

        return Json(new {result = pass});
    }

For some reason i keep getting 500 Internal Service error. i know it's a really basic question and i would really appreciate your help.

Are you sure the URL is correct? If you debug the MVC app and add breakpoint to the CheckFollow method. Does it stop there? — Tacud, Mar 23 '17 at 16:44

Your return statement probably should be:

return Json(new {result = pass}, JsonRequestBehavior.AllowGet);

Pertinent explanation of the AllowGet: Why is JsonRequestBehavior needed?
