New field not appearing in “Sitefinity Dynamic items Field C

I am using sitefinity 6.3. I have a have created Sitefinity Dynamic items Field Control Selector for one of my field which contains text,date, image and choices.\

Initially it generated just Title and Publication Field to appear in the grid when i select this dynamic module items.

    <sf:FlatSelector ID="itemsSelector" runat="server" ItemType="Telerik.Sitefinity.GenericContent.Model.Content"
            DataKeyNames="Id" ShowSelectedFilter="false" AllowPaging="false" PageSize="10" AllowMultipleSelection="true"
            AllowSearching="true" ShowProvidersList="false" InclueAllProvidersOption="true"
            SearchBoxTitleText="Filter by Title" ShowHeader="true"
    ServiceUrl="~/Sitefinity/Services/DynamicModules/Data.svc/live/">
            <DataMembers>
                <sf:DataMemberInfo runat="server" Name="Title" HeaderText='Title'>
                    <strong>Title.Value</strong>
                </sf:DataMemberInfo>
                <sf:DataMemberInfo runat="server" Name="PublicationDate" HeaderText='Date'>
                    <span>PublicationDate ? PublicationDate.sitefinityLocaleFormat('dd MMM, yyyy') : ""</span>
                </sf:DataMemberInfo>
            </DataMembers>
        </sf:FlatSelector>

Later I added two new fields in it

    <sf:DataMemberInfo  runat="server" Name="SpeakerCategory" HeaderText='Speaker Category'>
                     SpeakerCategory.Text
                </sf:DataMemberInfo>
    <sf:DataMemberInfo runat="server" Name="Photo" HeaderText='Photo'  IsExtendedSearchField="true">
                     <img sys:src="Photo[0].ChildItemAdditionalInfo" width="80" height="80"  />
                </sf:DataMemberInfo> 

And able to view when i am adding the items. But in edit mode i am not able to see new fiels.
any Idea what's wron i am doing

It ended up a caching issue while i remember i have atleast tried it a dozen time.
