columns is changing

[Former user]

Hi,

I am creating columns variable with dynamic data but every time the variable is creating three times when the page is loaded for example:

['id','name', 'title'] # this is the correct list
['id', 'name'] # incorrect
['id','name', 'title']

this is what is the logger is returning when I log the columns. Each time when I hit the URL it is printing three times.

Sorry, but I don't understand the issue. Please describe it more precisely with some code samples.
