Hi Ramakrishnan,
you can use the below code to post comments in newsfeed. I think this will helps you.
var feedManagerEndpoint;  
// Get the SPAppWebUrl parameter from the query string and build  
// the feed manager endpoint.  
$(document).ready(function () {  
    var appweburl;  
    var params = document.URL.split("?")[1].split("&");  
    for (var i = 0; i < params.length; i = i + 1) {  
        var param = params[i].split("=");  
        if (param[0] === "SPAppWebUrl") appweburl = param[1];  
    feedManagerEndpoint = decodeURIComponent(appweburl)+ "/_api/social.feed";  
    postToMyFeed();  
// Publish a post to the current user's feed by using the   
// "<app web URL>/_api/social.feed/my/Feed/Post" endpoint.  
function postToMyFeed() {  
    $.ajax( {  
        url: feedManagerEndpoint + "/my/Feed/Post",  
        type: "POST",  
        data: JSON.stringify( {   
            'restCreationData':{  
                '__metadata':{   
                    'type':'SP.Social.SocialRestPostCreationData'  
                'ID':null,   
                'creationData':{   
                    '__metadata':{   
                        'type':'SP.Social.SocialPostCreationData'  
                'ContentText':'This post was published using REST.',  
                'UpdateStatusText':false  
        headers: {   
            "accept": "application/json;odata=verbose",  
            "content-type":"application/json;odata=verbose",  
            "X-RequestDigest": $("#__REQUESTDIGEST").val()  
        success: getMyFeed,  
        error: function (xhr, ajaxOptions, thrownError) {   
            alert("POST error:\n" + xhr.status + "\n" + thrownError);
