Not sure it’s the best code but I’ve tested something here that works :
(function ($) {
// copy of the WP inline edit post
var wp_inline_edit = inlineEditPost.edit;
// override
inlineEditPost.edit = function (id) {
// WP edit function
wp_inline_edit.apply(this, arguments);
// get post ID
var post_id = 0;
if (typeof( id ) === 'object') {
post_id = parseInt(this.getId(id));
}
if (post_id > 0 && typeof mp_data !== 'undefined' && $.inArray( post_id, mp_data.ids ) > -1 ) {
var edit_row = $('#edit-' + post_id);
edit_row.find('.my_class').prop('checked', true);
}
}
})(jQuery);
It seems you have to do it this way.
