Finally I fixed the problem,
It is cause of calling script from Code behind:
Dim Script As String = String.Format("highlight({0},{1},{2});", List, WinPartyColor, LosePartyColor)
I have change is as follows, now it's working fine.
Dim Script As String = "highlight(" + List + ",'" + WinPartyColor + "','" + LosePartyColor + "');"
