OnCreateView not called in a dialogfragment from a fragment

I have a fragment that executes or display a dialog fragment once a button is clicked. This dialog fragment displays a table generated by code, however when I try to click the button on this is displayed
enter image description here

And when I trace it in the LogCat the dialog fragments onCreateView is not called. Can somebody help or explain this to me?. Im not that good in android programming yet and I know i still have a lot to learn.

Here is the code of the fragment that calls the dialog fragment

public class fragment_schedule extends Fragment {

...............


public fragment_schedule(ArrayList<SubjSchedule> subj){
subject = subj;
}
@SuppressWarnings("deprecation")
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {

..................

showlstbtn = (Button) rootView.findViewById(R.id.button_showlstschd);
showlstbtn.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View v) {

// TODO Auto-generated method stub
FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
ft.addToBackStack(null);
DialogFragment dialog = ShowLstDialog.newInstance(subject);
dialog.show(ft, "dialog");
}

});

..........


and heres my dialog fragment

public class ShowLstDialog extends DialogFragment {

private static final String TAG = ShowLstDialog.class.getSimpleName();
public static Context mContext;
public static TableLayout tl;
public static TableRow trh;
private static ArrayList<SubjSchedule> subject= new ArrayList<SubjSchedule>();

public static DialogFragment newInstance(ArrayList<SubjSchedule> subj) {
// TODO Auto-generated method stub
DialogFragment f = new DialogFragment();
subject = subj;
Log.v(TAG, subject.size()+"");
return f;
}



@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
Log.v(TAG, "OnCreateView: " + subject.size()+"");
View rootView = inflater.inflate(R.layout.fragment_dialog_showlst, container);
//mEditText = (EditText) view.findViewById(R.id.txt_your_name);
Log.v(TAG, "OnCreateView: " + subject.size()+"");
getDialog().setTitle("");
tl = (TableLayout) rootView.findViewById(R.id.tablelayout_schedlst);
trh = new TableRow(getActivity());
TextView[] tvh = new TextView[3];
for(int i=0; i<3; i++){
tvh[i] = new TextView(getActivity());
tvh[i].setBackgroundResource(R.drawable.green2);
tvh[i].setTextColor(getResources().getColor(R.color.LightCyan));
tvh[i].setGravity(Gravity.CENTER);
tvh[i].setPadding(30, 3, 30, 3);
//tvh[i].setLayoutParams(params);
trh.addView(tvh[i]);

}

tvh[0].setText("Subject");
tvh[1].setText("Description");
tvh[2].setText("Instructor");

TableRow[] tr = new TableRow[subject.size()];
for(int i=0; i<subject.size();i++){
tr[i] = new TableRow(getActivity());
TextView[] tv1 = new TextView[3];


for(int k=0; k<3; k++){
tv1[k] = new TextView(getActivity());
tv1[k].setBackgroundResource(R.drawable.btn_default_disabled_holo_dark);
tv1[k].setTextColor(getResources().getColor(R.color.list_background_pressed));
tv1[k].setGravity(Gravity.CENTER);
tv1[k].setPadding(30, 3, 30, 3);
//tvh[i].setLayoutParams(params);
tr[i].addView(tv1[i]);

}

tv1[0].setText(subject.get(i).getcn());
tv1[1].setText(subject.get(i).getd());
tv1[2].setText(subject.get(i).geti());
tl.addView(tr[i]);

}
return rootView;
}



}


and here is the xml file of the dialog fragment

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:background="@color/LightCyan"
android:scrollbars="vertical" >

<HorizontalScrollView
android:id="@+id/horizontalScrollView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >

<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal" >

<TableLayout
android:id="@+id/tablelayout_schedlst"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="*" >
</TableLayout>
</RelativeLayout>
</HorizontalScrollView>
</ScrollView>

</RelativeLayout>

Answer

Change this

public static DialogFragment newInstance(ArrayList<SubjSchedule> subj) {
    // TODO Auto-generated method stub
    DialogFragment f = new DialogFragment();
    subject = subj;
    Log.v(TAG, subject.size()+"");
    return f;
}

to

public static ShowLstDialog newInstance(ArrayList<SubjSchedule> subj) {
    // TODO Auto-generated method stub
    ShowLstDialog f = new ShowLstDialog();
    subject = subj;
    Log.v(TAG, subject.size()+"");
    return f;
}
