HTML Button calling Query calling EXEC_SP

Aware2014

From an HTML button, I am trying to call a query, and that query executes an EXEC_SP stored procedure.

Here is the HTML button code

onclick="var param = {}; param ['Section']='Books'; AwareApp.runQueryWithParams('Query123',params,AwareApp.getPanelId('main',params,'Main'))">Book Info

Here is the Query Rule Code

EXEC_SP 'SP_BOOKINFO' WITH '@paramBookSection'={Section} RETURN Books

Can you confirm what the parameter syntax should be in the Query Rule code?

{Section}

is not working.

BTW, I did change param to params in the above code, but still no luck.
