Solve it!

 var onMouseDown = function ( event ) {
	 
    document.addEventListener( 'mousemove', onMouseMove, false );
	document.addEventListener( 'mouseup', onMouseUp, false );
	this.dispatchEvent( startEvent );

};
	var onMouseUp = function( event ) {

		if ( scope.enabled === false ) return;

		event.stopPropagation();
		document.removeEventListener( 'mousemove', onMouseMove );
		document.removeEventListener( 'mouseup', onMouseUp );
		this.dispatchEvent( endEvent );

	}

    document.addEventListener( 'mousedown', onMouseDown, false );
    document.addEventListener( 'mouseup', onMouseUp, false );
