Make contentType also an option to set

[geeForceOne]

I'm working with a legacy Software and I can only make the serviceUrl work if I can set the contentType of $.ajax to "application/json; charset=utf-8". Would be nice if this could also be passed as an option in a future release. Many thanks.

            that.currentRequest = $.ajax({
                url: serviceUrl,
                data: params,
                type: options.type,
             contentType: opitons.contentType, 
                dataType: options.dataType
            }).done(function (data) {
                var result;
                that.currentRequest = null;
                result = options.transformResult(data);
                that.processResponse(result, q, cacheKey);
                options.onSearchComplete.call(that.element, q, result.suggestions);
            }).fail(function (jqXHR, textStatus, errorThrown) {
                options.onSearchError.call(that.element, q, jqXHR, textStatus, errorThrown);
            });
