Insert a copy of Attachment into a Chatter Feed as a File for Sharing on custom object


I need to add 'custom object' attachments to the chatter feed automatically. I have the following code but i'm facing some issues 

trigger AttachFileToCustomFeed on Attachment (after insert) {
 ID customId;
 list<FeedItem> listOfFeedFiles = new List<FeedItem>();
    for(Attachment attachment :{
        string checkIfCase = string.valueof(attachment.Description); {
        customId= attachment.ParentId;
        FeedItem post = new FeedItem();
        post.ParentId = customId;
        post.Body = 'Attachment added';
        post.Type = 'ContentPost';
        post.ContentData = attachment.body;
        post.ContentFileName = attachment.Name;
        post.Title = attachment.Name; listOfFeedFiles.add(post);
      insert listOfFeedFiles;

but i'm gettiing the below error
'Invalid field ContentData for SObject FeedItem'
If I comment the 'ContentData' then i'm getting this
'Invalid field ContentFileName for SObject FeedItem'.
Can anyone please help in this issue.
Thanks in advance.
