Custom Book Report of QWeb type

While running a simple Book Report of Qweb pdf report type, I face a problem.

Goal: To run a book report that allows the books to be shown in pdf output for a given Author and Title.  When the report is run, a wizard pops up where there are Author and Title search fields.  After that the Get Report button is clicked. The report output is expected instead the following error occurs.

The report doesn't launch, instead errors with a message below: 

"AttributeError: type object 'x_book.report.wizard' has no attribute 'get_report'.
