Filters related to date are not working

I have provided full xml of my grid page.
Below is the url from where you can download it.

I am facing the issue realted to date filters.
For example I have one field work experience year.
So Please check Reg Date Filter and work experience filter in above code.
And provide me proper solution for that.

Before a week all filters are working fine but now I am facing the error in this two filter.
It cannot able to search anything.
Like we have disabled that filters.

Rohit.  As your page is all custom fields,  there is no way for us to install it in an org and debug it.  Can you more specifically describe what you are trying to do and what is happening (Expected results, actual results).  Maybe include screenshots of  your setup?
