Qt c++ QSqlQueryModel example needed

(Please note this job was reposed from another account and changed, Sorry for the inconvenience) This is a very simple job. There is an example in the link below of a generic QSqlQueryModel in c++ and is used with qml. We already have an example almost working. We can query the sqlite database and get the correct number of rows in the listview in qml but the RoleNames which are set in the c++ and should be very easily accessible in qml are not setting right. We need the class working with the code as is shown in the official code from the website link, we are not needing you to re-write your own class. Just need the bug fixing. We need you to fix this error. anyone who can do this for a reasonable price then we would look into hiring you for various jobs of the same nature. We have several other examples which we would also need doing. (For an experienced programmer this should be very easy) Check our example below for reference.

The only reason we can't do this ourselves is that i have never installed 3rd party things before into qt and the manual is all in chinese. With the help of google chrome and google translate the we could pretty much understand the manual but due to never installing a 3rd party plugin before we weren't to clear on how to do it. So what we need is for you to get the example in the two links below working and then a simple instruction manual on how to install the plugin and the source code of the example send through to us for compilation.
