theme customization: change control value on button click

Code in functions.php

<script type="text/javascript">
(function($){
        jQuery(document).ready(function(){
	        $(".create-new-menu-submit").on("click",function(){

		        $("#customize-control-footer_menu_text input").val("Menu Name");

	        });
        });
})(jQuery);
</script>

create-new-menu-submit is a class of a button, clicking on which should change the value of a control ‘footer_menu_text’. What is wrong with my jquery? I am not aware of codes. Just copy and paste them to try it out. Please help me out with this. Thanks.
