How to create inputtext cascanding LOV

Question

hi how can one refresh cascanding lov my use case is i have <af:selectOneChoice which list the name of provience and i have <af:inputText which list city using <af:autoSuggestBehavior base on the provience i selected and i have subub in <af:inputText listing surbub using <af:autoSuggestBehavior it list based on the city i have select ,at the moment when i select provience and go to city it list only one value in the list but if i type 2 letters of exisisting cityit list, even if there is more than one values in database,the subub also list the same values ,and another thing is if i change the selection of provience and go and select another province and what to select another city and anothe subub it list the previous city name and previous suburb name it does not change according to new provience selection.the first city i choose when the page load its the only one displaying all the time,even if i restart the application,my problem is my <af:inputText does not list more than one values it always list one value if is city it only list one city if its subub it only list one subub,how can i refresh two inputtext so it can display values according to currently provience selected lov and display all values not only the first one selected .am in jdeveloper 11.1.1.6.0
Here's the scenario
1. i have 3 views witch are ProvienceVO,CityVo,SububVo they where created from theire entity
2. ProvienceVO it list the provience name
3. CityVo it list cityname and citycode,it got view criteria which got cityname and provience they all use operator start with,i did not use parameter in the query,i only use parameter in my view criteria
4. i got sububVO it list subub name it releate to cityvo using citycode,i also have view criteria which pass parameter subub and use operator startwith
5.in my application module i got two method which list the two views cityvo,subub based on the provience selected
6 in my bean class i got a method which listen which city,subub is selected it also pass the currently selected provience to city
7. I have wired all the LOVs correctly and it is working properly in ADF BC tester.
for example where it does not work
1 select provience in the list,but when i go to my inputtext it does not list values according to first lov selection.
2 select provience in the first list, but when i what to make selection in second lov i only get one values even if there is more values from database,this happen in city lov
3. select provience in the first list,select city,but when i come to select subub inputtext it only list one values it does not change even if i try to search other surbub it always return same surbubname value
4.if i type n in the inputtext it does not list available name Which start with n e.g for new york it only find new york if i type new than it will display new york ,after i type atleast 3 letters
Here's the code snippet of jspx:
<td width="53%" height="26">
                      <af:selectOneChoice
                                          label="#{bindings.ProvinceViewVO1.label}"

                      </af:selectOneChoice>
                    </td>
                  </tr><tr>
                    <td width="47%" height="19">
                      <af:outputLabel value="City" id="ol11"
                                      showRequired="true"/>
                    </td>
                    <td width="53%" height="19">
                        <af:inputText label="#{bindings.Cityname.hints.label}" columns="20"
                                        maximumLength="#{bindings.Cityname.hints.precision}"
                                        shortDesc="#{bindings.Cityname.hints.tooltip}"
                                        id="itc4" simple="true"
                                      value="#{pageFlowScope.orgDetailsBean.addressBean.city}"
                                      partialTriggers="soc4"
                                      valueChangeListener="#{pageFlowScope.addressbean.subValue}"
                                      autoSubmit="true">
                            <af:autoSuggestBehavior suggestedItems="#{pageFlowScope.addressbean.getSuggestedCities}"/>
                      </af:inputText>
                    </td>
                  </tr><tr>
                    <td width="47%">
                      <af:outputLabel value="Suburb" id="ol14"
                                      showRequired="true"/>
                    </td>
                    <td width="53%">
                       <af:inputText label="#{bindings.Suburb.hints.label}" columns="20"
                                        maximumLength="#{bindings.Suburb.hints.precision}"
                                        shortDesc="#{bindings.Suburb.hints.tooltip}"
                                        id="itcs4" simple="true"
                                     value="#{pageFlowScope.orgDetailsBean.addressBean.suburb}"
                                     valueChangeListener="#{pageFlowScope.addressbean.sububValue}"
                                     partialTriggers="itc4" autoSubmit="true">
                            <af:autoSuggestBehavior suggestedItems="#{pageFlowScope.addressbean.getSuggestedsbub}"/>
                          </af:inputText>
                    </td>I hope I have explained this well. If it's not clear please let me know.
Has anyone come across this scenario or know how to resolve this
