You need to register yourself for the AH events
I copy paste my code

-- AH events
self:RegisterEvent("AUCTION_HOUSE_CLOSED");
self:RegisterEvent("AUCTION_HOUSE_SHOW");

self:RegisterEvent("AUCTION_HOUSE_BROWSE_RESULTS_UPDATED");
self:RegisterEvent("ITEM_SEARCH_RESULTS_UPDATED");
self:RegisterEvent("COMMODITY_SEARCH_RESULTS_UPDATED");

if ( event == "AUCTION_HOUSE_BROWSE_RESULTS_UPDATED" ) then
--AHB_Data["function LogTextLine"](event);
local bri = C_AuctionHouse.GetBrowseResults();
local tempBrowseResults= { };
for _, v in pairs(bri) do
local ik = v["itemKey"];
local id = ik["itemID"];
local ilvl = ik["itemLevel"];
local iki = C_AuctionHouse.GetItemKeyInfo(ik);
local itemName = nil;
if ( iki ) then itemName = iki["itemName"]; end
local q = v["totalQuantity"];
local p = v["minPrice"];
if ( itemName ) then
AHB_Data["function LogTextLine"](string.format("browse results updated - id:[%d] - ilvl:[%d] - name:[%s] - q:[%.2f] - p:[%.2f]",id,ilvl,itemName,q,p));
if ( ahBrowseResultsNew[itemName] == nil ) then ahBrowseResultsNew[itemName] = {}; end
local silvl = string.format("%d",ilvl);
ahBrowseResultsNew[itemName][silvl] = { id, ilvl, itemName, q, p };
-- if we have directly enquired for this item, mark it as done
--if ( ahBrowseResults[itemName] ) then
-- ahBrowseResults[itemName][silvl] = { 0 };
--end
-- if we are refreshing the list from Excel
-- clear out this entry so we do nto ask again
-- this may not work for entries with multiple ilvls
if ( #ahAuctionHouseListItemsFromExcel > 0 ) then
for i=1, #ahAuctionHouseListItemsFromExcel do
if ( ahAuctionHouseListItemsFromExcel[i] == itemName ) then
AHB_Data["function LogTextLine"](string.format("clearing excel item list query - name:[%s] ilvl:[%d]",itemName,ilvl));
ahAuctionHouseListItemsFromExcel[i] = "";
break;
end
end
end -- manual update from excel
end -- if itemName
end -- for all browse results in list
end

if ( event == "ITEM_SEARCH_RESULTS_UPDATED" ) then
--AHB_Data["function LogTextLine"](event);

--AHB_Data["function LogTextLine"](string.format("%s - id:[%d] name:[%s] ilvl:[%d]",event,id,tostring(itemName),ilvl));
local numResults = C_AuctionHouse.GetNumItemSearchResults(ik);
-- weird case getting 0 results
if ( itemName and ilvl > 0 and numResults > 0 ) then
-- in the same list we assume ilvl is the same
-- and depending on sort order we need to get smallest price
local minPrice = -1;
local qAtMinPrice = 0;
for i = 1, numResults do
local v = C_AuctionHouse.GetItemSearchResultInfo( ik, i );
local q = v["quantity"];
local p = v["buyoutAmount"];
if ( minPrice == -1 or p < minPrice ) then minPrice = p; qAtMinPrice = q; end
end
