kendo grid is taking more time to load when using kendo editor inside a template - kendo-ui

Question

I am trying to load the documents on click of a button which is inside a grid but it is creating a new pages for every row and it is taking more time how to resolve it using kendo editor template or another specific methods.
// open window
function openWin(id) {
var myWindow = $("#" + id);
var did = id.replace("win", "doc");
console.log("Value from DID", did);
var rid = Number(id.replace("win", ""));
kendo.ui.progress($(".k-window"), true);
myWindow.data("kendoWindow").center().open();
$.ajax({
type: "POST",
url: "",
data: JSON.stringify(rid),
dataType: "json",
contentType: 'application/json; charset=utf-8',
success: function(data) {
kendo.ui.progress($(".k-window"), false);
$("#" + did).data("kendoEditor").value(data);
},
error: function() {
alert("Error occured!!");
}
});
}
// column definition
{
field: "Document",
template: docTemplateFunction,
title: "Document Intake",
width: "250px",
editable: "inline"
}
// template definition
function docTemplateFunction(dataItem) {
var input = '<div id="win' + dataItem.id + '"><textarea id="doc' + dataItem.id + '" style="width:100%;" aria-label="editor"></textarea></div><button class="k-button" onclick="openWin(' + "'win" + dataItem.id + "'" + ')">Open Doc</button><span class="k-button k-state-disabled doc-btn"><i class="red k-icon k-i-close k-state-disabled"></i></span>';
return input;
}
