Text not display on screen

i have my code below

for i=1, levelObjectGrp.numChildren,1 do  
 local child = levelObjectGrp[i]  
 print ('in falllop')  
  
 local textPost = display.newText( child.seq, child.x, child.y, "Verdana-Bold", 20 )  
  
 textPost:setTextColor( 255,255,0 )  
 objectSeqTextGrp.insert(textPost)  
end  

the text is not showing unless i remove the line above
objectSeqTextGrp.insert(textPost)

any idea how to include text into displaygroup? and yet to show them on screen
