Hi everyone,
First contribution around here (and on github!). I didn't find any "clear button" feature in the control enhanced by Ionic so I developed my own using this work as a base, and here is the result:
https://github.com/VinceOPS/ionic-clearable-input
Please feel free to let me know any issue, feedback... or if this feature was already built-in and I did all that for nothing 
!
Have a nice day.
PS - I discovered both AngularJS and Ionic at the same time, few days ago, so I'll gladly accept any critic regarding my coding style with these frameworks! Thanks.
