I have a jqxgrid with a column that has columntype:'checkbox'. I would like to make the size of the checkbox bigger. I tried with javascript with something like 

`$(".jqx-checkbox-default").children().css("width","19px");`

but it doesn't work as i should as when i check a box all the checkboxes in the grid are again getting smaller. I also tried with cellrenderer: 

```
<div style="position: absolute; top: 50%; left: 50%; margin-top: -7px; margin-left: -10px; cursor: auto;" id="jqxWidget3d79f0d1" tabindex="0" class="jqx-widget jqx-checkbox">
    <div class="jqx-checkbox-default jqx-fill-state-normal jqx-rc-all">
        <div style="width: 19px; height: 19px;">
            <span style="width: 19px; height: 19px;"></span>
        </div>
    </div>
    <div style="clear: both;">
    </div>
</div>

```

but with this i cannot check (also there is the problem with the widget id).
Is there a more "normal" solution?

Thanks, Alex
