Remove Check from Checkbox

Hi.
I have a checkbox in a repeater table row with values set from server connect. All these checkboxes are unchecked by default.
User can check multiple checkboxes as required, and perform an operation.
On success event of that operation, I load the repeater server connect again and all the values are refreshed, but the checkboxes still remain checked.

How to uncheck all check boxes when data is loaded again?
