    delete_chat_message=function(messageId, calbackFunc){
    var results = {success: 0, id: messageId}
    
        /* Model to delete the chat message*/
        AjaxChatMessage.remove({id: messageId}, function(err, data) {
            console.log('here');
            if (err) {
                results.success = 0;
            }else{
                results.success = 1;
            }
