Kendo datasource change read url on request start

I am currently doing this to change the read url dynamically on my kendo datasource. The datasource is used for a kendoautocomplete text box and for each key typed the list of suggestions are fetched through a get request.

  requestStart: function (e) {
                    var text = $('#txtMail').val();
                        e.sender.transport.options.read.url = "/Feed/AutoCompleteUser?text=" + text + "&limit=10";
                    }

This works fine the first time , but consequent request's are exactly same as the first request it never hits this piece of code. What am i missing?

Please advice.

You can just add a data parameter for your read request, like so, in this case, as the request is sent as a get, it will append the query with the fields inside your data object.

By adding the function like this, it will get called every time you make a request.

function getRequestParameters() {
    return {
        text: $('#txtMail').val(),
        limit: 10
    };
}

var dataSource = new kendo.data.DataSource({
    transport: {
        read: {
            url: "http://demos.telerik.com/kendo-ui/service/products",
            data: getRequestParameters,
            dataType: "jsonp"
        }
    }
});
