"This" changed context after upgrading to typescript, resourceZonesConfig not working

[mcm]

I have a problem with a changing meaning of "this".
We have updated a solution to typescript from javascript but our scheduler is proving really difficult as the meaning of "this" changes after the update.
I have attatched a picture where you can see that 1. "this" in typescript(new) and refers to the innerTpl() itself. But in 2. (old, javascript) "this" refers a data record containing relevant information
3 Is the code with changing behavior.

For context, this is what I am trying to achieve (And worked in our old solution)

Please show the TS you wrote that broke things and the old code so we can compare.

Hello Mats, thanks for answering.
That would be quite difficult as the entire solution have changed, this is a migration that have been in progress for a years time now, and we first now realized we were missing the prices in the cells.

I have been trying to figure out how/when resurceZonesConfig is called in order to maybe realize how to parse parameters to it.

Ok very hard to help you without seeing the actual code....

In other words, I can see that the property resourceZonesConfig is used internally by the scheduler only.
When resourceZonesConfig.innerTpl() is called, the "this" contexts inside innerTpl() should stay the same, right?

Yes
