NestedList and ItemTemplate

Hi there,



Is there a way to refresh the NestedList ItemTemplate without reloading all the data in the NestedList?



I mean, in the ItemTextTpl I have code calling to functions that calculates the numbers to show in each listitem but only apply first time NestedList is loaded. If the result of the calculation change, the list doesn't update the numbers because need to reapply the ItemTextTpl



Thanks in advance
