Using CMS 7 (7.0.586.16) I can't figure out how what I'm doing wrong since the value in the PropertyString isn't persisted in the dynamic content settings.

	[DynamicContentPlugIn(DisplayName = "Test")]
	public class PriceDynamicContentPlugin : IDynamicContentView
	{
		public PriceDynamicContentPlugin()
		{
			Properties = new PropertyDataCollection { new PropertyString() };
		}
 
		public string State { get; set; }
 
		public PropertyDataCollection Properties { get; private set; }
 
		public void Render(TextWriter writer)
		{
			writer.Write(State);
		}
	}
