I am trying to edit the content of a page using experience manager in Tridion2013 SP1 for a DD4T site. When I click on the rich text box, Content from the textbox disappears at sudden. I have checked the markup for the page which looks fine. I am using the same DD4T view and same CP on a different page for which site edit is working.
<section class="centerCol">
