The regex pattern validation error shows up when a decimal value is added to the field

[Dimple16]

I am using this plugin to support adding a decimal number input in the ionic iOS app where the region uses comma as the decimal separator. Though I can add decimal values, the pattern validation error shows up for the input field due to pattern="[0-9]*". Please let me know if there is a better way of using it, or is there any workaround for the mentioned issue?
