How to call MVC Action using Jquery AJAX and then submit form in MVC?

Question

On my MVC View I have button:

<input id="btnSave" type="submit" name="Save" value="Save" />

When I click this button I need call one Action, do some stuff there and then Submit my form.

I have this jQuery:

$('#btnSave').click(function () {    
    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

Then I want to submit my form. In Controller I have 2 Actions:

public ActionResult SaveDetailedInfo(Option[] Options)
{
    return Json(new { status = "Success", message = "Success" });
}

[HttpPost]
public ActionResult Save()
{ 
    return RedirectToAction("Index", "Home");
}

The problem is when I have type="submit" in my button, I can't reach SaveDetailedInfo Action, cause ajax gives me error, but when I remove type="submit", ajax works fine, but Save Action never executes.

Please, any ideas how to execute both Actions? I thought maybe after Ajax > Success try to add type=submit through jquery and use .click(), but it sounds strange to me.

Use preventDefault() to stop the event of submit button and in ajax call success submit the form using submit():

$('#btnSave').click(function (e) {
    e.preventDefault(); // <------------------ stop default behaviour of button
    var element = this;    
    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            if (data.status == "Success") {
                alert("Done");
                $(element).closest("form").submit(); //<------------ submit form
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});
