how to call function of user control in another user control both of them in the same master page
<p>i have two user controls , both of them in the same master page 
 in one of them i have a counter , and the the other one there is some code that increment and decrement that counter 
if i make a reload to the whole page the counter works well and get the right number , but if i made any changes in the second user control it didn't feel it till the next page reload </p>
