```
{{ row[col.key] | col.filter }}

```

I have filter in a col.filter variable. I tried creating eval filter like mentioned in following link, <https://github.com/fabpot/Twig-extensions/pull/53/files> and also tried <https://github.com/marcj/twig-apply_filter-bundle> or calling like

```
{{ row[col.key] | eval(col.filter) }}

```

or 

```
{{ eval(row[col.key] , col.filter) }}

```

But it doesn't work.

Demo for the issue is here,
