Using jQuery trying to change background-color of text box but not working in wordpress

Here is jQuery code which I am using .

<input class="jscolor" name="jscolor" value="F078A0" />
<input name="my_txtbox" type="text" id="my_txtbox_id" value="F078A0" />

<script type="text/javascript">
jQuery('.jscolor').on('change', function($) {
    var color = jQuery('.jscolor').val();
    jQuery('#my_txtbox_id').text(color);
    jQuery('#my_txtbox_id').attr('value',color);
    jQuery('#my_txtbox_id').css('background-color',color);
});
</script>

I put this in my plugin function file #my_txtbox_id get value of color but background-color CSS is not working.

How to solve this?
