Why this `Area` `signal` is not detecting my mouse events (input_event)

I just added CollsionShape and Area to the voxels (3D tiles) of my games. I create the Area with generate_faces and create a signal to dectec de mouse_detect_area:

func generate_faces():

	var surfaceTool : SurfaceTool
	
	surfaceTool = SurfaceTool.new()
	surfaceTool.begin(Mesh.PRIMITIVE_TRIANGLES)
	
	for i in range(VOXELDATA.voxelFaces.size()):
		
		if notNeig[i]:
			
			for j in range(VOXELDATA.voxelFaces[i].size()):
				
				surfaceTool.add_vertex(VOXELDATA.voxelVertices[VOXELDATA.voxelFaces[i][j]])
	
	
	surfaceTool.generate_normals()
	
	mesh = surfaceTool.commit()
	meshInstance.mesh = mesh
	
	
	bodyShape = mesh.create_trimesh_shape()
	collisionShapeBody.shape = bodyShape
	add_child(collisionShapeBody)
	
	
	areaShape = mesh.create_trimesh_shape()
	collisionShapeArea.shape = areaShape
	area.add_child(collisionShapeArea)
	add_child(area)
	
	area.connect("input_event", self, "_detect_area") # self is the StaticBody that contain the Area


func _detect_area():
	print("Collision detected")

Although CollisionShape and Area are created in the same way, CollisionShape are working, since I tested with a falling RidigBody; but Area is not, nothing appears in the Debugger when I click the voxels. I add an image with the scene and the scene tree: here

I tried to move the ´Area´ outside the chunk using Remote option to chech if there was some problem, but it is still not working.
