perform action on kendo window custom button click

[Ravi]

Hello,

by using the below code i am trying to open the kendo window on button click this is working fine. 
 function OpenWindow() {
        var dialog = $("#window-prototype").clone().kendoWindow({
            width: "500px",
            height: "280px",
            modal: false,
            resizable: true,
            actions: ["Custom", "Minimize", "Maximize", "Close"],
            title: "OrderEntry"
        }).show().data("kendoWindow").open().center();

my requirement is i need to perform some action on custom button click on kendo window.So I added event in the javascript function

 function OpenOrderEntry() {
            var dialog = $("#window-prototype").kendoWindow({
            width: "500px",
            height: "280px",
            modal: false,
            resizable: true,
            actions: ["Custom", "Minimize", "Maximize", "Close"],
            title: "OrderEntry"
        }).data("kendoWindow").wrapper.find(".k-custom").click(function (e) {
            alert("Custom action button clicked");
            e.preventDefault();
        });
        dialog.data("kendoWindow").open();   <== Error
    }

but it is throwing the below given error "Microsoft JScript runtime error: 'data(...)' is null or not an object".

Regards,
Ravi

Your chaining looks like it's breaking your value of dialog, because you were returning the jQuery object from the FIND method rather than the kendo window.  Try this:

function OpenOrderEntry() {

            var dialog = $("#window-prototype").kendoWindow({

            width: "500px",

            height: "280px",

            modal: false,

            resizable: true,

            actions: ["Custom", "Minimize", "Maximize", "Close"],

            title: "OrderEntry"

         }).data("kendoWindow");

     dialog.wrapper.find(".k-custom").click(function (e) {

             alert("Custom action button clicked");

             e.preventDefault();

         }); 

         dialog.data("kendoWindow").open();   <== Error

     }
