method is not getting called at client side using signalR

Question

I am building an auction site in 3-tier architecture.I have a method which is defined in AuctionHub.cs as follows:

 

public BAL.LiveAuctionBAL AuctionBid(string Lot_Id, string InputAmt, string vendorid, string V_AuctionID, string AddModBy, string OpenBidAmt, string Decrementbid, string LastBidAmount, string auctionEndTimer)

{

BAL.LiveAuctionBAL BAL = new BAL.LiveAuctionBAL();

string result = "";

string msg = "", message = "";

try

{

BAL.Auction_Id = Convert.ToInt32(V_AuctionID);

BAL.Lot_Id = Convert.ToInt32(Lot_Id);

BAL.Vendor_Id = Convert.ToInt32(vendorid);

BAL.Bid_Amount = Convert.ToDouble(InputAmt);

if (auctionEndTimer != "")

{

BAL.AuctionEndTimer = DateTime.Parse(auctionEndTimer.ToString());

}

else

{

BAL.AuctionEndTimer = Convert.ToDateTime("01/01/1900");

}

BAL.AddMod_By = AddModBy;

result = BAL.AddAuctionBid();

if (result != "")

{

msg = result;

}

}

catch

{

}

return BAL;

}

 

now I am calling this method at client side as follows:

jq(function () {

jq.connection.hub.start().done(function () {

chat.server.auctionbid(Lot_Id, InputAmt, vendorid, V_AuctionID, AddModBy, OpenBidAmt, Decrementbid, LastBidAmount, auctionEndTimer);

}

 

but its not working...please help me with this.Its very urgent for me..Thanks in advance
