semiCircle._containsPoint(point) always returns false

[MedAb94]

I have the next code:

 let cellPolygone = L.semiCircle(cell.lanLng, {
                    radius: cell.range * 1000,
                    startAngle: cell.angle - 30,
                    stopAngle: cell.angle + 30
                }).addTo(this.map)
let p = this.home_center 
//this.home_center is a L.latLng object
 console.log(cellPolygone._containsPoint(p))

I tried the all the next forms but with the same result

p = {x:x_coord, y:y_coord} 
p = [x_coord, y_coord]
p = L.point(x_coord, y_coord)

It logs always false
