Struggling to update the initial value displayed in TouchSpin, it seems like there is no direct way to do it. While it's possible to change other values like the maximum value, attempts to set the initval directly have failed.
$("input[name='touchspin']").TouchSpin({initval: 1}); //doesn't work
$("input[name='touchspin']").trigger("touchspin.updatesettings", {max: 100}); // successfully changes max value
$("input[name='touchspin']").trigger("touchspin.updatesettings", {value: 1}); // doesn't work
