Echo Web Framework

Is there anyway on how to do this?
Currently, I got a problem with my current apps and i'm guessing that i need to reload my ApplicationInstance
I'm trying to add session to my apps by using the setContextProperty, when i try to add something inside the setContextProperty by using the button's action listener...I'm only able to add one value of row for each table (weird huh..O.o)
but when i hardcode the setContextProperty() inside the codes, i'm able to insert more than one value...So my guess is in the reloading of ApplicationInstance...

So..is there any simple way to do it?
