i Am getting the value check in console but the checkbox is not showing checked.

the code and console is given below

       console.log(elem1)
      res[0].cut_type_sub.forEach((elem2, index) => {elem2;
        console.log(elem2.id)
         if(elem1 == elem2.id)
         {
          //--If elem1 equal elem2
          this.fish_cuttype[index].checked = !this.fish_cuttype[index].checked;
           console.log('Done',elem1 == elem2.id,this.fish_cuttype[index])
         }
       });
