Targeting a column filter if a column before is not visible

I recently asked this question:

https://datatables.net/forums/discussion/54071/how-to-clear-a-filter-upon-column-visibility-button-click#latest

This appeared to work - BUT if I have column visibility enabled and one of the columns before the above scenario of filtering the column are hidden then the target to reset the filter won't work because it is taking into account the invisible column in the numbering which I am referencing.

Is there a way to get this to work? I have tried targeting like this:

$('#example thead tr:eq(1) th:visible:eq('+column+') input').val('')

But this doesn't work - I need either a way of targeting visible inputs or to target the filter input css ID but I can't seem to be able to match the filter name e.g. #filter-customer on the input to the column number being passed back from column-visibility.dt

As my columns are in DataTables the ideal would be to get the column name back rather than the ID, anyway to do that?

I tried:

table.columns(column).name()
and
table.column(column).name()

with no luck.
