Steps to reproduce

1. Install attached zip package on 10.10 Nuxeo instance
2. Create a Folder
3. Within Folder create a few documents of type "Test Doc"
4. Navigate back to the Folder
5. Click on tab "Test Doc Filter"
6. Expand Filters
7. Enter in values for Count Min and Count Max to filter results
8. Press form Clear button

Expected Results:  The Clear button clears all form fields and results are updated
Actual Results: The Clear button clears all form fields but results aren't updated

Repeat steps 5 - 7 but also enter in a value for Dublincore Nature

The Clear button does not update the results when using Min and Max (from choosing Between in predicate in PP)
