What do you mean by "help button on the left pane"?
For which code? (C++? QML/JS?)

For the clang code model, you can start Qt Creator within a run time 
environment containing

   QT_LOGGING_RULES=qtc.clangcodemodel.hover=true

to see debugging output when doing a mouse hover on e.g. identifiers. 
This will query the help data base, basically triggering the F1 code 
path (the tooltip will contain a F1 symbol do indicate that F1 can be 
pressed to go to documentation). A sucessfull run looks like this:

   qtc.clangcodemodel.hover: Requesting tooltip info at 68
   qtc.clangcodemodel.hover: Processing tooltip info "QCoreApplication"
   qtc.clangcodemodel.hover: Querying help manager with 
"QCoreApplication" "QCoreApplication" ClassOrNamespace
   qtc.clangcodemodel.hover:   Match!

Please put answer to these questions and the failing example into a bug 
report.

Note that the clang code model is more sensitive to invalid code than 
the built-in one. Error recovery is not that great.
