Ng-focus triggered on different time for web-mobile vs Ionic(ion view)

I have input element that has ng-focus attribute to set with a function like so.

 <input ng-focus="someFunc()" ..........></input>

In web-mobile, this triggered as soon as I touch/hit input element.

However in Ionic View, this triggered only after I touch/hit it and start to typing some stuff in it which is problem for me.

–> How would I make the ng-focus to be triggered as it gets touched? (not start to typing) :frowning:
