Android : How to change the color text Android Bootstrap button

I want to change the Text's color in a AndroidBootStrap Button.

I tried with android:textColor="@color/Pink" but the text still in black.

Peace of code including my bootstrap button in xml:

<com.beardedhen.androidbootstrap.BootstrapButton
                                android:layout_width="fill_parent"
                                android:layout_height="wrap_content"
                                bootstrapbutton:bb_size="xsmall"
                                android:text="Esporte"
                                android:textColor="@color/Pink"
                                bootstrapbutton:bb_icon_left="fa-check-circle-o"
                               bootstrapbutton:bb_text_alignment="left"
                                bootstrapbutton:bb_text_gravity="left"
                                />   

Any idea?
