How to make an iOS App recognize a number as a phone number

I am creating an iOS application using the Apache Cordova tools for Visual Studio and I am trying to find a way to make my application recognize a user-inputted number as a phone number.

The app deals with calling drivers and cabs and allows the users to enter the drivers' numbers but has a pre-determined, hard coded list of the cab numbers included as well. When i open the app, the hard coded numbers show up blue and with a hyperlink to them with the standard phone options iOS menu but the numbers the users input into a table don't turn blue immediately after they are entered, you either have to back out of the app and come back in, or calling one of the cab numbers and backing out of the call also enables the blue hyperlink.

Is there a tag i can attach to or a method i can call to make the app recognize that these numbers are phone numbers? Or is there a certain refresh call that would reload the data and automatically make these inputted numbers attached to a hyperlink like the hard coded numbers?
