Current behavior
After typing something into filter it stays there untill we manually remove it or change it

Expected behavior
It would be great to be able to reset filters from our code. For instance if someone type an email and move all the users from source to target I would like to clear the filters. Now it stays as we typed it with no way to reset it.

• Angular version: 5.0.X

• PrimeNG version: 4.3.0-rc.2

How about adding a reset() method?

That would be great

Added resetFilter with an example in doc.

[showSourceFilter]="someVarOnCloseBecomesZeroOnOpenBecomesOne > 0"
[showTargetFilter]="someVarOnCloseBecomesZeroOnOpenBecomesOne > 0"

this way you can enable filterBar onModalOpen, and disable filterBar onModalClose
