Cannot set input check checked = "checked" via jQuery

I have a table whose rows contain switch groups:

<td class="usegsm">
  <input type="hidden" class="use-gsm" value='<%# DataBinder.Eval(Container.DataItem, "use_gsm") %>' />
  <input type="hidden" class="use-gsm-lineup" value='<%# DataBinder.Eval(Container.DataItem, "use_gsm_lineup") %>' />
  <input type="radio" id="radio1-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" name="radio-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" class="events-lineups" />
  <label for="radio1-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>">Events &amp; Lineups</label>
  <input type="radio" id="radio2-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" name="radio-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" class="events" />
  <label for="radio2-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>">Events</label>
  <input type="radio" id="radio3-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" name="radio-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>" class="none" checked="checked" />
  <label for="radio3-<%# DataBinder.Eval(Container.DataItem, "MatchId") %>">None</label>
</td>

When the page loads (inside document.ready), I call this function to check the correct switches based on the above values ​​for input.use-gsmand input.use-gsm-lineup:

function setGsmButtonStates() {
      $('td.usegsm').buttonset(); /* http://jqueryui.com/demos/button/#radio */
      $('td.usegsm').each(function(i) {
        var use_gsm = $(this).children('input.use-gsm').val();
        var use_gsm_lineup = $(this).children('input.use-gsm-lineup').val();

        if (use_gsm == 'Y' && use_gsm_lineup == 'Y') {
          $(this).children('input.events-lineups').attr('checked', true);
        }
        else if (use_gsm == 'Y' && use_gsm_lineup != 'Y') {
          $(this).children('input.events').attr('checked', true);
        }
        else {
          $(this).children('input.none').attr('checked', true);
        }

      });
    }

For some reason, installation .attr('checked',true)or even .attr('checked','checked')has no effect.

Am I using wrong $.each()or .attr()?

, - span. .

function setGsmButtonStates() { 
      $('td.usegsm').each(function(i) { 
        var use_gsm = $(this).children('input.use-gsm').val(); 
        var use_gsm_lineup = $(this).children('input.use-gsm-lineup').val(); 

        if (use_gsm == 'Y' && use_gsm_lineup == 'Y') { 
          $(this).children('input.events-lineups').attr('checked', true); 
        } 
        else if (use_gsm == 'Y' && use_gsm_lineup != 'Y') { 
          $(this).children('input.events').attr('checked', true); 
        } 
        else { 
          $(this).children('input.none').attr('checked', true); 
        }
