How to detect touch hold on sprite on mobile?

[korgoth]

This code is working fine on desktop (returns true when I hold the mouse button on the sprite ) but not on mobile or in Google Chrome Canary emulator ( always returns false ).

this.flyButton = this.add.sprite(100,100,'button');this.flyButton.inputEnabled = true;update: function() {    console.log(this.flyButton.input.pointerDown());}

What am I doing wrong? ( Phaser 2.1.3 )
