Script not works (ASP.NET MVC) - asp.net

Question

I have script for recording video
Here is code of it
var fileName;
stop.onclick = function () {
record.disabled = false;
stop.disabled = true;
window.onbeforeunload = null; //Solve trouble with deleting video
preview.src = '';
fileName = Math.round(Math.random() * 99999999) + 99999999;
console.log(fileName);
var full_url = document.URL; // Get current url
var url_array = full_url.split('/') // Split the string into an array with / as separator
var id = url_array[url_array.length - 1]; // Get the last part of the array (-1)
function save() {
$.ajax({
type: 'Post',
dataType: 'Json',
data: {
link: fileName,
id: id,
},
url: '#Url.Action("LinkWriter", "Interwier")',
success: function (da) {
if (da.Result === "Success") {
alert("lol");
} else {
alert('Error' + da.Message);
}
},
error: function (da) {
alert('Error');
}
});
}
I try to get url with this row var id = url_array[url_array.length - 1]; // Get the last part of the array (-1)
and with this code write to table filename
$.ajax({
type: 'Post',
dataType: 'Json',
data: {
link: fileName,
id: id,
},
url: '#Url.Action("LinkWriter", "Interwier")',
success: function (da) {
if (da.Result === "Success") {
alert("lol");
} else {
alert('Error' + da.Message);
}
},
error: function (da) {
alert('Error');
}
});
}
but it not works.
There is my Action method for it
[HttpPost]
public ActionResult LinkWriter(string link, int id) {
Link link_ = new Link
{
Link1 = link,
Interwier_Id = id,
};
db.Link.Add(link_);
db.SaveChanges();
return View();
}
But it not works. Where is my mistake?
UPDATE
As I understood not works this
function save() {
$.ajax({
type: 'Post',
dataType: 'Json',
data: {
link: fileName,
id: id,
},
url: '#Url.Action("LinkWriter", "Interwier")',
success: function (da) {
if (da.Result === "Success") {
alert("lol");
} else {
alert('Error' + da.Message);
}
},
error: function (da) {
alert('Error');
}
});
}
