Request.Form POSTED variable empty

I have verified by using the browser debugger / network monitor that I am sending in a variable in an AJAX call called "search" and in the monitor it shows in the header as "search=test". I am trying to access this variable in the code behind but can't seem to find it? Here is my code for front and back-end, am I missing something?

Code Behind :

public class AJAXSearchLog : IHttpHandler {

    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        string searchTerm = Convert.ToString(HttpContext.Current.Request.Form["search"]);
        if(!string.IsNullOrEmpty(searchTerm)){
           AspDotNetStorefrontCore.DB.ExecuteSQL("insert into TribSearch(SearchTerm,CustomerID,LocaleSetting) values(" + DB.SQuote(CommonLogic.Ellipses(searchTerm, 97, true)) + "," + '0' + "," + DB.SQuote("en-us") + ")");
        }
        context.Response.Clear();
        context.Response.Write(searchTerm);
        context.Response.End();
    }

    public bool IsReusable {
        get {
            return false;
        }
    }

}

Front-End

  window.onbeforeunload = function(e) {
        if ($("#searchBox_text").val().length >= 2) {
        var _search = $("#searchBox_text").val();
            var url = "/AJAXSearchLog.ashx";
            $.ajax({
                async: false,
                type: 'POST',
                url: url,
                data: {'search': _search},
                contentType: 'application/json;',
                dataType: 'json',
                success: function(result) {
                    alert(result);
                },
                error: function(xhr, textStatus, errorThrown) {
                    console.log('error');
                }
            });
        }
    };

I have found that the data wasn't getting passed through when the contentType was set to 'application/json'. Also, to read the POST variable, Request.Params[] was needed. Here are the 2 lines of code that I changed :

in the front-end - contentType: 'application/x-www-form-urlencoded; charset=UTF-8',

in the back-end - string searchTerm = Convert.ToString(context.Request.Params["search"]);
