jquery script doesn't work

[leon_temp@163.com]

hi, I setup a private instance and run following scripts:
logData 0
combineSteps
navigate https://xxx.com
exec document.getElementById("userName").value = "xxx"
exec document.getElementById("password").value = "xxx"
logData 1
clickAndWait id=btnLogin
sleep 5
execAndWait $("button[class$='icon-setting']").trigger("vclick")
execAndWait $(".moremenu-icon").trigger("vclick")

Howerver, after sleep, the last 2 scripts are not executed. Actually, I tried many ways to make them works, include use commands "click", "exec document...", all of them not works. I hope the jquery script can works because our web site is very complex with many javascript codes.
