Changing Jquery FlexGrid's data

Question

I am having a flex grid. I need to change the data which is showing in that.

In $(document).ready() I am calling a function and I am getting the result.Now what i want is to get data from db using another query.So I just made a function, in that i am adding the needed values to fetch the data in the url.This function is calling when I click a button .But the request is not going .So that is not changing.Please Help me. Thanks

 $(document).ready(function() {

            getAllData(); //first call

            $(".datebetweenList").click(function() {

                    getDataBetweenDates(); //secondcall change in url


     });     
    });


// Calls First
  function getAllData() {

            $("#flex1").flexigrid

                    ({
                        url: '../Handlers/AjaxGetData.ashx?isFlexi=<%=Request.QueryString["ass"]%>&bid=' + document.getElementById("<%=ddlBranch.ClientID%>").value,
