Steps:

1. First grid in documentation
2. Select filter in 'Is admin' column. First with is true. Second with is false
3. After selecting is false, you can see that displaying data are still the ones with true value.

Current behavior

I debugged this issue in my app. Even if you select false, the filter model sends true.

Filter Model when is true is selected

Filter Model when is false is selected.

Something could be wrong with the on change handler of the filter selection?

Root cause is the change made in
#14733

Hi @arminmeh ,
the problem seems to be here Boolean("false") evaluates to true, sorry I didn't notice it while working on #14733
I think the better approach to convert values to boolean type is String(value).toLowerCase() === 'true'
we should also probably need to check further that we are handling falsy values correctly or not :(
should I create a PR or are you willing to fix it yourself?
