Hi everybody,

I have the following markup

 <div class="col-md-2 col-lg-2">
            <input type="number" class="form-control" 
                   data-sm:number-format data-sm:number ng-show="!showHeightSm"
                   min="0" max="8" name="heightFt" id="heightFt"
                   ng-model="currentGuest.heightFt" ng-change="updateHeightSm(currentGuest.heightFt, currentGuest.heightIn)"/>
            <label class="col-md-1 control-label" title="Ft.">Ft.</label>
            <div class="field-validation-error">
                <span ng-show="(form.editGuestGeneralForm.heightFt.$error.min || form.editGuestGeneralForm.heightFt.$error.max) && form.editGuestGeneralForm.heightFt.$dirty">
                    @String.Format(Messages.mustBeBetweenXandY, Labels.heightInFeet, 0, 8)
                </span>
            </div>
        </div>
        <div class="col-md-2 col-lg-2">
            <input type="number" class="form-control"
                   data-sm:number-format data-sm:number ng-show="!showHeightSm"
                   min="0" max="11" name="heightIn" id="heightIn"
                   ng-model="currentGuest.heightIn" ng-change="updateHeightSm(currentGuest.heightFt, currentGuest.heightIn)"/>
            <label class="col-md-1 control-label" title="In.">In.</label>
            <div class="field-validation-error">
                <span ng-show="(form.editGuestGeneralForm.heightIn.$error.min || form.editGuestGeneralForm.heightIn.$error.max) && form.editGuestGeneralForm.heightIn.$dirty">
                    @String.Format(Messages.mustBeBetweenXandY, Labels.heightInInches, 0, 11)
                </span>
            </div>
        </div>

I have height in sm and height in inches which is calculated column in the table (e.g. HeightSm is a normal column and Height is computed column in a table). I added two extra columns heightFt and heightIn to the view model. I'm trying to re-calculate heightSm when I am entering values in Ft and In columns. The problem is that ng-change is similar to interactiveChange and fires too often, even when I press backspace when delete the value. Is there another method to use?

Thanks in advance.
