yes loop.js is in the same directory

Loop.js has a fucntion which has the variant list as parameter.
Here i am using power cells defined by me as a element on which the loop is being called on.
Below is the code for loop.js
Qt Code: 
  1. var PCell = new Array;
  2. var i = 0;
  3. var powerComponent = Qt.createComponent("PowerCell.qml");
  4.  
  5. function setPowerCells(pList)
  6. {
  7.     PCell = pList;
  8.     for(i = 0; i < (PCell.length - 1);i+2)
  9.         {
  10.         PCell.iconValue = pList[i];
  11.         PCell.instrumentedStatus = pList[i+1];
  12.     }
  13. }

This is the code for power cell to be called by js file

Qt Code: 
  1. import Qt 4.7
  2.  
  3. Item {
  4.     id: button
  5.     signal clicked
  6.     property string iconValue
  7.     property string instrumentedStatus
  8.     signal name
  9.     property bool toggled: false
  10.     width: 133
  11.     height: 135
  12.     Image {
  13.         id:button_img
  14.         anchors.fill: button
  15.         anchors.margins: mouseArea.pressed
  16.         smooth: true
  17.         source: { if ("instrumented" == button.instrumentedStatus)
  18.                     return "instrumentedButton.png"
  19.                   else if ("non-instrumented" ==  button.instrumentedStatus)
  20.                       return "nonInstrumentedButton.png"
  21.         }
  22.  
  23.         Image {
  24.             x:37
  25.             y:40
  26.             width: 54
  27.             height: 56
  28.             id: instrumentIcon
  29.             source: button.iconValue
  30.  
  31.         }
  32.  
  33.     }
  34.  
  35.     MouseArea {
  36.         id: mouseArea
  37.         anchors.fill: parent
  38.         onClicked: {
  39.             button.clicked()
  40.         }
  41.     }
