Espresso Web - perform(DriverAtoms.webKeys("0.11")) only inputs 11

When interacting with webviews using this code

onWebView().withElement(findElement(Locator.ID, "payment-amount")).perform(DriverAtoms.webKeys("0.11"))

it only enters 11 without the decimal. I am trying to figure out how I can include decimal point in sending keys to webview.

Any idea?
