Add post render in custom methods - Sharepoint

Call post render events will help to render the html design after the page load event.
------------------------------------------------------------------
Create a new calback.js file for render functions:

function DW_AddPostRenderCallback(renderCtx, newCallback) {
    DW_AddRenderCallback(renderCtx, 'OnPostRender', newCallback, false);
}

function DW_AddRenderCallback(renderCtx, callbackType, newCallback, enforceUnique) {
    if (Boolean(renderCtx) && typeof newCallback == 'function' && callbackType != '') {
        var renderCallbacks = renderCtx[callbackType];

        if (renderCallbacks == null)
            renderCtx[callbackType] = newCallback;
        else if (typeof renderCallbacks == "function") {
            if (!Boolean(enforceUnique) || String(renderCallbacks) != String(newCallback)) {
                var array = [];

                array.push(renderCallbacks);
                array.push(newCallback);
                renderCtx[callbackType] = array;
            }
        }
        else if (typeof renderCallbacks == "object") {
            var exists = false;

            if (Boolean(enforceUnique)) {
                for (var i = 0; i < renderCallbacks.length; i++) {
                    if (renderCallbacks[i] == newCallback) {
                        exists = true;
                        break;
                    }
                }
            }
            if (!exists)
                renderCtx[callbackType].push(newCallback);
        }
    }
}

function DW_CallFunctionWithErrorHandling(fn, c, erv, execCtx) {
    if (DWClientRenderer.IsDebugMode(c)) {
        return fn();
    }
    try {
        return fn();
    }
    catch (e) {
        if (c.Errors == null)
            c.Errors = [];
        try {
            e.ExecutionContext = execCtx;
            if (Boolean(DWClientRenderer.AddCallStackInfoToErrors) && typeof execCtx == "object" && null != execCtx) {
                execCtx.CallStack = ULSGetCallstack(DW_CallFunctionWithErrorHandling.caller);
            }
        }
        catch (ignoreErr) { }
        c.Errors.push(e);
        return erv;
    }
}

DWClientRenderer = {
    GlobalDebugMode: false,
    AddCallStackInfoToErrors: false,
    RenderErrors: true
};
DWClientRenderer.IsDebugMode = function (renderCtx) {
    if (typeof renderCtx != "undefined" && null != renderCtx && typeof renderCtx.DebugMode != "undefined") {
        return Boolean(renderCtx.DebugMode);
    }
    else {
        return Boolean(DWClientRenderer.GlobalDebugMode);
    }
};

//function ULSSwq() {
//    var o = new Object;
//    o.ULSTeamName = "Microsoft SharePoint Foundation";
//    o.ULSFileName = "clientrenderer.commentedjs";
//    return o;
//}

var DWClientRenderer;

DWClientRenderer._ExecuteRenderCallbacks = function (renderCtx, callbackType) {
    var templateExecContext = {
        Operation: callbackType
    };
    var fn = function () {
        // ULSSwq();            ;
        return DWClientRenderer._ExecuteRenderCallbacksWorker(renderCtx, callbackType, templateExecContext);
    };

    return DW_CallFunctionWithErrorHandling(fn, renderCtx, null, templateExecContext);
};

DWClientRenderer._ExecuteRenderCallbacksWorker = function (renderCtx, callbackType, templateExecContext) {
    if (!renderCtx || callbackType == null || callbackType == '')
        return;
    var renderCallbacks = renderCtx[callbackType];

    if (renderCallbacks == null)
        return;
    if (typeof renderCallbacks == "function") {
        templateExecContext.TemplateFunction = renderCallbacks;
        renderCallbacks(renderCtx);
    }
    else if (typeof renderCallbacks == "object") {
        var numCallbacks = renderCallbacks.length;

        if (numCallbacks && typeof numCallbacks == "number") {
            for (var n = 0; n < Number(numCallbacks) ; n++) {
                if (typeof renderCallbacks[n] == "function") {
                    templateExecContext.TemplateFunction = renderCallbacks[n];
                    renderCallbacks[n](renderCtx);
                }
            }
        }
    }
};
---------------------------------------------------------------------------------------
Call in Document.ready function

$(document).ready(function () {
    var dw_NewsComments = new DigitalWorkplace.NewsHub.dwNewsComments();
    //if($('.comments-row').size() > 0)    {
      
    dw_NewsComments.GetNewsComments().then(function (dw_commentsCtx) {
        if (dw_commentsCtx !== null)
            DWClientRenderer._ExecuteRenderCallbacks(dw_commentsCtx, 'OnPostRender');
        });   
});
