Hello everyone, I want to know how to uncheck checkbox, when user push to delete element (elsewhere) but not in the checkbox, i tried jquery with "onclick" with no success, btw my check box list and delete buttons with data come from two different partials, is there any specific october approach...?

Your approach seems correct to me. I think, however, that you have some error in your java script code. Maybe you can share some of your code with us so it's easier to help.
