You're never setting the flag field, which you use to populate the mtt list. 

Replace the first column in your first page block:
  
<apex:column ><apex:inputcheckbox value="{!a.value3}" /> </apex:column>


with:
  
<apex:column ><apex:inputcheckbox value="{!a.flag}" /> </apex:column>

Also, please learn how to read your own code, as this was an obvious issue that you could easily fix.
