WebPart not getting refreshed on changing properties from powershell

Question

I edited the Content property of a Content Editor Web part via powershell but when I first view the page, it is not getting reflected. When i click edit once , I see my changes . What could the issue for the changes to the web part not getting reflected even on Page refresh ?

  Function EditProperties($SiteCollectionURL) {

    $Web = Get-SPWeb $SiteCollectionURL

    $PublishingWeb = [Microsoft.SharePoint.Publishing.PublishingWeb]::GetPublishingWeb($web)

    $PublishingPages = $PublishingWeb.GetPublishingPages()      

    foreach ($Page in $PublishingPages)
    {  
        $Page.CheckOut()

        $WebPartManager = $web.GetLimitedWebPartManager($Page.Url,[System.Web.UI.WebControls.WebParts.PersonalizationScope]::Shared)

        foreach($webPart in $WebPartManager.WebParts)
        {

            if($webPart.GetType() -eq [Microsoft.SharePoint.WebPartPages.ContentEditorWebPart])
            {    

               if($webPart.Title.Equals("LinkWebPart")){

                  $oldXmlElement = $webPart.Content;
                  $oldXmlElement.InnerText =  'Edited Content here!';  
                  $webpart.Content = $oldXmlElement
                }

             $webPartManager.SaveChanges($webPart);
            }


}
    $page.CheckIn("CEWP Updated") 
    $Page.ListItem.File.Publish("CEWP Updated")
}

}

Try the following:

$xmlDoc = New-Object System.Xml.XmlDocument
$contentXml = $xmlDoc.CreateElement("Content") 

$contentXml.InnerText = 'Edited Content here!'
$webpart.Content = $contentXml
