PeoplePicker on custom forms via SP Designer in SP 2013

The default NewForm and EditForm for lists/libraries have a different people picker column than when you create a custom New or Edit form using SP Designer. When using the default list forms and they include a people picker field, the dropdown list of options as you type to search for people works as expected. If you create a new custom list form in SP Designer, the same people picker field does’t have the dropdown list of options as you type. The custom form people picker looks closer to the SP 2010 version. I am trying to get the custom form people picker to match the default.

This is the code in the custom form that calls the control:

<SharePoint:FormField runat=”server” id=”ff5{$Pos}” ControlMode=”New” FieldName=”Requestor” __designer:bind=”{ddwrt:DataBind(‘i’,concat(‘ff5′,$Pos),’Value’,’ValueChanged’,’ID’,ddwrt:EscapeDelims(string(@ID)),’@Requestor’)}”/>
<SharePoint:FieldDescription runat=”server” id=”ff5description{$Pos}” FieldName=”Requestor” ControlMode=”New”/>

Here is the custom form people picker:

Here is the full people picker:

I have not seen anyone successfully post an answer to this online. I have tried the option discussed here which involves changing the control name to “ClientPeoplePicker” but this option will not allow me to actually save the record. 

Anyone with some thoughts on making the custom form people picker work?
