you should write below code:
$(function () {
$("#btnSave").on("click", function (e) {
$.ajax({
type: "Post",
url: '/Home/Add',
data: { Content: $("#editorControl").data("kendoEditor").value() },
datatype: 'json',
success: function (data) {
location.href = '/Home/Index';
},
error: function (e) {
console.log(e);
}
});
});
});
