Hide File link from Chatter Feed

Hi All,

I have a requirement to hide the File Link in chatter feed. I have a VF Page and I am able to do this using the below code.

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
            <script>
               $j = $.noConflict();
               $j(document).ready(function(){

                    $j('#publisherAttachContentPost').hide();  
               });
                </script>

<div id="chatter-container">
        <chatter:feedWithFollowers entityId="{!Object1__c.id}" showHeader ="true" oncomplete="refreshStatus()" reRender="statusPanel" />
    </div>

But this works only when show Feed is clicked and the record is opened or refreshed.
