How to show a modal view upon a click of a textfield but without the keyboard appearing?

I have a situation where the user clicks on a textfield, and then a modal pops up with a list of account numbers where selecting an account number will make the modal go away and the selected value entered in the textfield.

I have so far made it to a stage where clicking on the textfield fires the modal popup event, but since the input type is text, the keyboard shows up too.

How can I go about this?

Thanks in advance. (I’m a newbie to ionic and using iOS platform)
