angularjs smart table (st-table) issue with ngInclude - angularjs

Question

I had a page working fine with st-table in angularjs (1.8.x).
Ref: Smart Table Website or on Git Hub.
Because the page was becoming too big (HTML), as a quick fix I put the sections into diff HTML files and then used ng-include on main page. But since then the st-search stopped working.
Check the code:
<table class="table table-condense table-striped table-bordered" ng-hide="vmModelMg.currentModel.exclusionParts.length==0" st-safe-src="vmModelMg.currentModel.exclusionParts" st-table="dispExclPartsList">
<thead style="overflow-y:scroll;">
<tr>
<th colspan="2" style="width: 30%; padding-right: 10px;border-right:none;">
<a class="btn btn-primary pull-left" ng-click="vmModelMg.refreshExclusionPartsManual()">Refresh</a>
</th>
<th colspan="3" style="width: 35%;border-right:none;border-left:none;">
Show only Active? :
<!--'{{vmModelMg.isActiveModelFilterExPt}}'-->
<input type="checkbox" st-search="isActive" value="{{vmModelMg.isActiveModelFilterExPt}}" ng-model="vmModelMg.isActiveModelFilterExPt" ng-true-value="true" ng-false-value="" />
</th>
<th style="width: 35%;border-left:none;">
<a class="btn btn-primary pull-right" ng-click="vmModelMg.addNewExclusionPart()">Add new Exclusion Part</a>
</th>
</tr>
<tr>
<th style="width: 10%;"></th>
<th st-sort="partCode" style="width: 15%;">Part Code</th>
<th style="width: 15%;">Transmission Type</th>
<th st-sort="isActive" style="width: 15%;">Is Active?</th>
<th style="width: 45%;">Notes</th>
</tr>
</thead>
<tbody style="overflow-y:scroll;max-height:300px;">
<tr ng-show="dispExclPartsList.length==0">
<td colspan="5" style="width:100%;">
<div class="alert alert-info">
No Exclusion Parts found.
</div>
</td>
</tr>
<tr ng-repeat="exclPartRec in dispExclPartsList">
... td values here ...
</tr>
</tbody>
</table>
I included this using code below:
<ng-include src="'/Scripts/app/Views/manageModels.exclusionParts.html'"></ng-include>
Can someone please advise why if I paste this code in main page it works & if in the ngInclude it doesn't. Now, when I say it doesn't it doesn't show records when tab is loaded. If I click on "Show Active only" checkbox, the filter starts working. But, if same code is on single page, it shows records as soon as I load the tab.
