Enable copy-paste for edittext in PopupWindow in android

Question

I use PopupWindow to get some data from users. Surprisingly, I cannot select the text inside the EditText field, which is a requirement as I want the user to be able to copy and paste here. I explicitly used android: textIsSelectable = "true" for my EditText. Here are the attributes that I use for EditText.

       <EditText
        android:layout_width="match_parent"
        android:layout_height="48dp"
        android:id="@+id/emailEdit"
        android:inputType="textEmailAddress"
        android:textIsSelectable="true"
        android:drawableLeft="@drawable/email"
        android:drawablePadding="16dp"
        android:layout_margin="@dimen/actionable_horizontal_margin"
        android:singleLine="true"
        android:hint="Email"
        />

I also set popup.setFocusable (true). Is there anything else that needs to be done? My copied copy works great for other EditTexts in actions and snippets.

PS I do not want to use custom actions with the clipboard.
