Exclude Checkbox not linked with exFilterExternallyTriggered

[GMEHTA1981]

Here is the live example.

Basically, the exclude checkbox will fire search onClick / onKeyUp
However, when using the feature exFilterExternallyTriggered : true
We would like all the filter options to work same way.

Checkbox checked should not trigger independent search.
