Data not getting displayed in second view in UI5

[Former Member]

Hi Gurus,

I am facing few issue in developing an application in UI5 for which i need some help.

1. When i am navigating from first view(input.view.xml) to second view(plant.view.xml) data is not getting displayed from local json file.

2. I cannot navigate back from second view to first view and also not getting any error in developer console.Please find the attached code for your reference.
